Removable cores
Enabling the whole core section to be removed allowsunsurpassed access to dampers and duct internals, withouthaving to remove the main frame, avoiding unnecessary damageto walls or ceilings.
Quarter turn fasteners are the standard removable core fitting.Using a discrete clip on the main frame, and a zinc plated pin heldsecurely by a neoprene washer in the core frame, the fastenersare completey secure when in position, but allow quick and easycore removal when needed.
The bracket’s slim design means grille depths are unchangedfrom standard, non removable core models.
Wing head pins are available as an alternative to slotted headpints to allow removal by hand if required.
Pins and brackets are supplied unpainted.
Hinged core
As with removable cores, hinged cores use a main and coreframe.
Zinc plated piano hinge is fitted to the full length of the hingedside, and countersunk cross headed bolts secure the core in it’sclosed position.
Chromed cam fasteners are optional.

Countersunk fixing holes: Code suffix FH
Countersunk fixing holes in the grille frame arethe easiest fitting method. Screws in the same
finish are supplied with the grille.
Concealed fixings: Code suffix CF
Consisting of L brackets with threaded ports, oneL bracket is fixed into the ductwork or plenum, the
other is riveted to the rear of the grille frame.Supplied bolts are then used to hold the grille into
the supporting structure.
Goalpost method: Code suffix GB
Normally used on linear slot diffusers, HVC hasmade this effective fixing method available to a
wider range of grilles with the addition of asecond bracket.
It enables the whole grille to be fully supportedby, and removable from the plenum.
This method is only suitable for linear grilles with0° blade, single / double deflection grilles, egg
crate grilles, curved blade grilles, and any othergrille with the removable or hinged core option
specified.
Fitting optionsGrilles
7
Push-in clip method: Code suffix PC
These sprung clips are compressed when thegrille is pushed into place. The outward force
provided then holds the grille securely in place.
This method has the advantage of requiring nodrilling or bolting, for maximum ease and causing
no damage to walls.
This fixing method is not suitable for use inceilings.
