Terminations

Standard Terminators (Type 1) allow Multi-Gard to be terminated into a standard pre-cast termination for Type C or Type 40 PVC.1. Remove watertight plugs in order to

assure total insertion of the Multi-Gardinnerducts.

2. Install terminators into male end ofMulti-Gard to full depth.

3. Replace watertight plugs into the terminator and tighten.

4. Insert prepared male end into the pre-cast terminator with print line facingupward. Solvent cement into place.

5. Use shim enclosed for terminator requiring a connection of Type C (4.35 O.D.) into a Type 40 (4.50 O.D.) termination.

Use a Type 6 Enclosure Terminator atentrances into metal or non-metallic enclosures above ground.1. Remove watertight plugs in order to

assure total insertion of the Multi-Gardinnerducts.

2. Install terminators into male end ofMulti-Gard to full depth.

3. Replace watertight plugs into the terminator and tighten.

4. Install threaded adapter over end of Multi-Gard using solvent cement. Insertadapter through enclosure hole and provide 4" locking ring.

5. Use shim enclosed for terminator requiring a connection of type C (4.35O.D.) termination.

The pass-through terminator is designed toallow for continuous ducts through the vault or hand hole for cable pulling.1. Install terminator into vault following steps

1 through 5 for standard Type 1 terminator.2. Cut innerduct of pass through kit 10" longer

than the width of the manhole. Add spacersas needed.

3. Upon completion, remove the watertightplugs and install innerducts to traverse manhole/handhole by cutting to lengthinserting into one side of handhole and raising or bowing center of innerduct spanto insert into the pass-through terminator on the opposite side. (See pass-through kitson page 22.)

Use a Type 1 Standard Terminator also at anentrance where a pre-cast terminator is notavailable or a knockout is used:1. Insert the male end section of Multi-Gard

4 inches past the inside wall of the vaultwith print line facing upward.

2. Remove the protective cap from the maleend of the Multi-Gard.

3. Remove the watertight plugs and insertthe terminator to full depth.

4. Install bell fitting over the end of Multi-Gard using solvent cement, andreplace plugs.

5. Slide Multi-Gard section until bell fitting isflush with inside, and then seal entrance asrequired by job specifications.

Use the jet terminator for jetting operations.1. Remove watertight plugs in order to assure

to total insertion.2. Apply standard grade solvent cement

(VC9962) to male end of Multi-Gard. Installjet terminator to insertion line.

3. Replace watertight plugs into terminator and tighten.

4. Apply standard grade solvent cement to terminator male end and insert into pre-castbell end. (Install PVC bell fitting in kit if pre-cast bell end is not available).

5. Use shim enclosed for terminator requiring a connection of Type C (4.35" O.D.) into aType 40 (4.50" O.D.) termination.

Multi-Gard® PVCTrenchingInstallation allows Multi-Gard in the trench to be placed one sectionat a time or over the trencher for continuous feed. Open trenchingwith Type C Multi-Gard is recom-mended for direct burial or concreteencased applications.

• Install one section at a time.• Multiple-cells are installed as soon as

product is placed.• Economical installation with

installation speed as fast as thetrencher can dig.

• Easy installation with standardequipment.

• Gasketed coupling body prevents conduit pulling apart during installation.

• Industry standard outer duct in TypeC is suitable for direct burial.

• Type 40 outer shell and Type 80 outershell are available where extra protection is necessary.

• Spacers inside outershell allow PVC innerduct internal movement allowing for more flexibility.

Features: Procedures:

Paved Areas In paved areas, the surface should be carefullycut to prevent unnecessary excessive width at the top of thetrench and help reduce the amount of surface to be repaved.

Trench Width For economical operation, particularly wherepaving is involved, the trench width should be no greater thanis needed to provide adequate working space. Generally, thisdimension is controlled by the types of excavating equipmentused. As a minimum, the trench must be 5 inches wider thanthe width of the conduit structure where backfill will be usedand 3 inches wider where concrete encasement will be used.Individual job specifications will dictate trench width.

Trench Bed Grade and level the trench bed. Where necessary, provide sand and/or other granular backfill as bedding material so the conduit will be evenly supported overthe length of each section.

Assembly On Top Of The Trench After preparing thetrench, the Multi-Gard can be assembled on top of the groundoutside of the trench by following the directions described onpage 5. Once joined together, the Multi-Gard can then be laidgently into the trench. Backfill according to the job specifications.

Trench Feeding Multi-Gard Using Rollers This procedureinvolves assembling the Multi-Gard above the ground. Afterthe first four or five lengths are assembled, place on top of thetrenching machine. The remainder of the duct can be attachedto the first section and assembled ahead of the trencher on theground directly above the intended place for the trench. As thetrencher advances forward, the Multi-Gard will lay itself intothe trench behind. Once placed in the trench, backfill accordingto the job specification.

Duct Proofing & Cable Installation

Duct Proofing for Cable Pulling

Use 175 or 250 CFM Compressor for maximum line blowingpotential. Choose pull line based on length of pull and tension expected.1. Remove all plugs in terminator at exit end and only the

plug being shot into on the entrance end.2. Turn threaded nozzle into terminator until tight, without

pull line or missiles to blow any debris or water whichmight have collected.

3. Open gate on nozzle to apply air to innerduct. Close gateafter any debris or water has been blown out.

4. Unscrew nozzle and thread pull line through eyelet in nozzle and tie to line blowing missile. Place pull line reelon stand for feeding.

5. Place line blowing missile into open innerduct and carefully open gate on nozzle.

6. Feed pull line off reel and keep slight tension to avoidrope packing in innerduct.

7. When using flat tape as pull line, use twisted blow line(RP142) to blow in and retrieve flat tape.

1-800-322-756623

Proofing for Jetting Cable

Use 375 CFM compressor for best results1. Attach polyethylene feed tube (1" SDR 13.5 for 4-way and

11/4" SDR 13.5 for 3-way) with coupling recommended forhigh speed air blowing systems to empty innerduct extension on jet-through terminator.

2. Assemble coupling according to high speed blowing system manufacturers recommended instructions.

3. Attach opposite end of polyethylene feed to high speedair speed machine.

4. Plug all unused holes in the Multi-Gard terminator at entry point and remove all plugs at exit terminator. Apply 100-110 PSI to the Multi-Gard innerduct. Close theair output valve and stop compressor. The innerduct is acceptable if a loss of 20 PSI or less happens within 2 minutes of pressurization. WARNING: NO PERSONNEL INMANHOLES DURING PRESSURE TEST.

5. Multi-Gard is ready for jetting cable procedures on page 24if air pressure is acceptable.

1-800-322-756624

Cable Installation Using Pulling EquipmentThe low co-efficient of friction of pre-lubricated PVC will allow pullsin excess of 4000' for Multi-Gard unless abrupt changes are in theroute. Pull speeds of 100-200 ft. per minute are acceptable.Cable pulling operations:1. Multi-Gard innerducts are pre-lubricated. Additional lubricant

may be used for longer pulls.2. Align the pull blocks or sheaves so the pull line passes directly

and freely from the innerduct entrance. Cable should be fedfrom the top of the reel.

3. Choose swivel with load rating at or below maximum pull limit.Attach swivel between pull line and cable pulling eye or basketgrip.

4. Maintain constant pulling tension to avoid stop/start. A monitoring device should be used to avoid over tensioning thecable. Most outside plant cables are rated for 600 lbs. Checkwith cable manufacturer for specific pulling tension.

5. Leave slack in each handhole where racking will be needed.

Cable Installation Using Jetting EquipmentMulti-Gard with the new Air-Gard™ gasket and pre-lubed PVCinnerduct is ideal for jetting cable. (Refer to pages 5 and 6 for Multi-Gard assembly in jetting applications).Jetting cable operations:1. Set up jetting equipment for easy accessibility to PE innerduct

secured to Multi-Gard.2. Blow foam carriers through innerduct until clean and dry.3. Multi-Gard is now ready for jetting according to high speed air

blowing system manufacturer’s instructions.4. Leave slack in each handhole where racking will be needed.

Duct Proofing and Cable Installation

Innerduct Racking Using Pulling EquipmentThe racking operation should be done after the cable has beenpulled through the Multi-Gard.1. Place PVC corrugated split innerduct over slack cable.2. Secure cable in innerduct against handhole/manhole wall out of way.

Innerduct Racking Using Jetting EquipmentThe racking operation should be done before the cable has beenjetted through the Multi-Gard, unless slack is needed in vault.1. Cut innerducts square and attach PE racking innerduct to PVC jet

terminator using coupling rated for high speed air blowing system.2. Assemble coupling according to coupling manufacturers’

recommended instructions.3. Rack innerduct against sides of vault at a maximum 18" radius

and attach PE innerduct to jet terminator on opposite side ofvault.

Cost Comparison Chart

1-800-322-756625

1. Eliminates the need to place innerducts into an empty conduit. Multi-Gardcontains factory installed innerducts.

2. Multi-Gard factory pre-installed PVC innerducts provide a straight path forthe placement of cable.

3. Reduced installation cost. The cost of installing innerducts is eliminated andinnerduct waste is eliminated.

4. Multi-Gard prelubrication formula provides the lowest coefficient of frictionavailable.

5. The Multi-Gard gasketed coupler system eliminates cementing sectionsexcept when boring or jetting.

6. Multi-Gard patented fixed bends and flexible bends incorporate “cut-through” resistant innerducts. Pre-installed engineered plastic innerductsprevent pull lines from cutting into the innerduct sidewall when pulling

around bends. Bends containing HDPE or PVC innerducts do not have thesame resistance to cut-through.

7. Open the trench just once. Multi-Gard allows customers additional cells toupgrade their Telecom Network System.

8. Multi-Gard factory installed innerducts allow more innerducts to be placedinside the 4" conduit (4 x 1.19" and 3 x 1.50"). When placing innerducts youare limited to (3 x 1.25" or 2 x 1.5") on many systems.

9. Multi-Gard factory installed innerducts avoid the risk of "neckdown". Neck-down occurs when innerducts are pulled past their tensile strength, causingthe plastic to stretch out.

10. All material arrives on the job site at the same time! Crews can beginassembly without waiting for additional material to deliver. After installingMulti-Gard there are no empty reels to return or dispose.

from Carlon Telecom Systems. Multi-Gard is acomplete system of outerducts with prein-stalled innerducts. Type C outerduct is recom-mended for direct burial with other wallthicknesses available for different applica-tions such as Type 40 PVC, Type 80 PVC,fiberglass for bridge crossings, and galva-nized steel for bridge head walls. EachMulti-Gard 20' section has a gasketedcoupling inside the bell end. The bell andcoupling push into the next section byhand without tools. The gasket seals theouterduct and innerducts, without theuse of cements, in one motion. Pre-installed innerducts have numerousadvantages over pulling innerductinto conduit. Three 11/2" l.D.innerducts or four 11/4" innerductsallow cable to be pulled at leasttwice as far as pulled innerduct,saving hand holes and time. Eachbend is manufactured using “cut-through” resistant innerduct toresist rope cutting through anadjacent occupied innerduct. TheMulti-Gard system is also both pul-lable and jettable.

New GasketingCarlon Telecom Systems has recentlyintroduced Air-Gard™ gaskets in theMulti-Gard multi-cell conduit systems. Thisnew system is the answer to both pulling andjetting cable placement. Jetting cable is growing inpopularity as Sherman and Reilly from Chattanooga,Tennessee gain acceptance of their Cable-Jet and Super-Jet® jet-ting machines. Multi-Gard was tested in a field trial using the Super-Jet®

hydraulic equipment supplied by Sherman and Reilly.

Jetting Cable into Multi-GardCarlon Telecom Systems and Electric Lightwave agreed to have NielsFugal Sons Construction jet cable into a section of Multi-Gard installed inthe International Center Industrial Park located in Salt Lake City, Utah.Electric Lightwave, a metropolitan access provider, is installing a bypassnetwork for the entire industrial park. Niels Fugal Sons was chosen for thetrial based on their considerable experience with Cable-Jet® equipment.A 96 Fiber 14mm HDPE jacketed cable was supplied by NorthernTelecom. The job layout consisted of 5,600' from end to end with twohand holes needing slack for future deployment. Dave Fox of Niels Fugalhad 23 years of experience with U.S. West many pulling cable. “I’ve

never seen one of these multi-cells work yet,” Dave said before the pro-ject started.

Jet Field Trial LayoutThe starting hand hole was prepared using standard SDR13.5 innerduct for flexibility from the SuperJet® hydraulicmachine into the Multi-Gard terminator in the hand hole.Each manhole was terminated using “pass-through” ter-minators, allowing innerduct to be plugged into the ter-minator on either side of the manhole. A compressor

with 375 CFM and 140 PSI capabilities supplied airto the Super-Jet® machine. Air alone was suppliedto one innerduct of the multi-cell to clean out anypossible debris resulting from unpluggedinnerduct terminators. Small foam sponges wereshot through each innerduct to further clean thesystem. Sherman and Reilly recommendedonly two to three ounces of Cable-Jet® lubri-cant be added to the already pre-lubricatedPVC innerducts in the Multi-Gard. A tarpwas laid out to keep the cable clean beforeinnerduct entry. Lastly, a small hollow“bullet” was attached to the end of thecable for cable alignment.

“It Works”Dave Fox pushed about 150 feet ofcable by hand and the Super-Jet®

hydraulic machine took it fromthere. Cable speeds approached210 feet per minute while thepressure maintained 110 PSI to120 PSI. (Speeds of 300 Feet +are obtainable using pneumaticunits) “It held the pressure. Itworks,” Dave said, as the cablewas feeding into the Multi-Gard without a problem. Thecable was successfully jetted5,600' in less than 29 minutes.

“This is the first multi-cell systemI’ve seen work. I would recom-

mend it if you’re needing four holesinstead of three.”

Pulling Cable into Multi-GardMulti-Gard multi-cell was originally designed for

cable pulling. Documented field trials of up to 7,400' at only280 pounds of pulling tension have been recorded. The PVC innerductslay straight. Conventional theory says PE used for pulling innerductsshould apply to pre-installed innerducts. This theory is invalid. The idea isto make pre-installed innerducts as straight as possible with the lowest co-efficient of friction between the cable and the innerduct surface. Multi-cellsuse an outershell and spacers to hold the innerducts in place. PE is only25% as stiff as PVC, causing even filled PE innerducts used in multi-cellsto “sag” between the spacers. This sagging causes increased pulling ten-sion and, consequently, shorter pulls. Multi-Gard PVC innerducts laystraight and are also prelubed in a process which reduces the co-efficientof friction below that of even pre-lubed PE. Carlon Telecom Systems PVCsmooth wall innerduct provides co-efficient of friction well below .10 rec-ommended by Bellcore using the Bellcore GR-356 procedures.

Planning for the FutureProtection and management of the cable to be placed is less expensiveand more useable with proper planning. The use of multi-cell conduit andadvanced cable placing techniques can provide for future growth whileprotecting the ever increasing traffic on the cables being installed.Protection will become more important as higher volumes of information

are transmitted. Multi-Gard reduces costs over traditional conduit placingmethods, while offering increased protection in one complete engineeredsystem.

More information is available on Multi-Gard by calling Carlon TelecomSystems at 1-800-322-7566.

Carlon Telecom Systems patented flexible bend allows changes in direc-tions and 0˚ to 90˚ bends. Each bend is manufactured using innerductmade of an engineered plastic designed to avoid pull rope cuttingthrough the innerduct into an adjacent occupied innerduct.

Only two to three ounces of Cable-Jet® lubricant (manufactured byAmerican Polywater® Inc.) are added to Multi-Gard® factory pre-lubricated innerducts.

Multi-Gard® jet layout requiredjetting cable through two man-holes using pass-through termi-nators. Innerduct was extendedfrom one side of the manhole tothe other side using only gasket-ed “pass-through” terminators.

A major telephonecompany sponsored acompetition to compareand evaluate the twoleading multi-cell conduitsystems currently availablein the communicationsindustry.

Under the supervisionof the telephone company, an independentcontractor was hired toinstall the two multi-cell conduit systemsmeeting standard installation requirements.Additionally, a consultantwas retained by thetelephone company to monitor the test pulls and preparea product evaluation for each multi-cell conduit system.

The following information was compiled from theconsultant’s report. Values stated were derived fromactual field measurements or calculated from field measurements.

Carlon’s multi-cell conduit system, Multi-Gard®,offered smooth wall PVC innerducts with factory appliedsilicone lining. The competitor’s multi-cell conduit systemoffered a longitudinal ribbed polyethylene, silicone linedinnerduct product.

The installation layout selected for the trial consistedof a 4,900-foot section that included numerous horizontaland vertical directional changes, eight manholes, and aroad bore. Additionally, record-breaking rainfall madethe competition even more intense.

The cable selected for the trial consisted of a six pair,copper cable with a low density polyethylene jacket.This particular cable was selected because it is approxi-mately the same weight and diameter as many fiber-optic cables. The low density polyethylene jacket placedthe evaluation under the worst possible coefficient offriction conditions.

Carlon’s Multi-Gardsystem successfullycompleted the trialpull with the test cable.The competitor’s systemcould not.

A 1/4" compositerope (braided polyeth-ylene over braidedpolyester) was blowninto the innerduct ofCarlon’s Multi-Gard.The force required topull the rope throughthe 4,900 feet was 27pounds. This force wasmeasured after therope rested in the

flooded innerduct for more than 10 hours.

The test cable required a maximum pull force of 440pounds to complete the 4,900 feet trial. At 4,173 feetinto the pull, the cable jacket yielded and the pull cameto a stop. The basket grip was re-installed on the cableand only 267 pounds of force was required to start thecable moving.

Using the values measured and the tension forecastingsoftware provided by the consultant, the coefficient offriction was calculated as follows:
