NOTE: If a top strut is to be installed on door, placetop section on sawhorses and position strut on topsection about 1" from the top of door. At each stilelocation drill 5/32" pilot holes through strut and stile,using care not to go through the section. Attachstrut to door (at center stiles only) using #14 x 5/8"sheet metal screws (steel doors) or 1/4" x 1" lagscrews (wood doors). DO NOT attach strut at endstile locations at this time, as it will be neces-sary to place LHR top bracket between strut anddoor in the next step.

Step 3Insert rollers in low headroom top brackets. Oneach side of door, insert each roller into horizontaltrack. Slide each low headroom bracket down thetop section until top section is tight against woodstop or steel jamb. If a top strut has been installedon the section, the top roller bracket will go betweenthe strut and the section, with the roller above thestrut. Line each low headroom top bracket up withthe side of the top section. Using both slots ineach low headroom bracket as a guide, drill 5/32"pilot holes in the center of each slot. Attach topbracket to end stile using (2) 1/4-20 x 17/8" carriagebolts & nuts for wood doors or (2) #14 x 5/8" sheetmetal screws for steel doors. (FIG. 3)
