VERTICAL TRACK ADJUSTMENT
Adjust the spacing of the vertical tracks from
HORIZONTAL TRACKS/ ADJUSTING TOP BRACKET
Use chain or cable to temporarily suspend the rear of the horizontal track assembly. Align the curved end of the horizontal track assembly with the top of the vertical track. Secure the horizontal track to the splice plate or flagangle using (2) 1/4” x 9/16” track bolts and hex flange nuts as shown in FIG
With tracks installed you can adjust the top brackets. Starting on one side, slide the top bracket roller(s) out against the horizontal track. Maintaining the slide’s position, tighten the 5/16” x 3/4” carriage bolt(s) and flange hex nut(s) to secure the top bracket slide(s) to the top bracket base. Repeat for other side.

WARNING
INSTALL SUPPORT BRACKETS TO SOLID STRUCTURAL MEMBERS ONLY. DO NOT INSTALL OVER DRY WALL OR PANELING. FAILURE TO INSTALL SUPPORT BRACKETS TO SOLID STRUCTURAL MEMBERS CAN CAUSE SEVERE OR FATAL INJURY.
WARNING
FAILURE TO USE PROPER NUMBER OF FASTENERS CAN RESULT IN SUDDEN SPRING TENSION RELEASE, CAUSING SEVERE OR FATAL INJURY.
NOTE: Spring pads must be securely anchored before proceeding, as shown in FIG
Attach the EBF’s (end bearing brackets) to the horizontal reinforcing angles using (2) 3/8” x 3/4” truss bolts and nuts, as shown in FIG L1, L2, L3.
Attach the EBF’s to the jambs using (2) 5/16” x
Install the Center Support Bracket(s) to the spring pads at the same elevation as the bearing in the EBF’s. Depending on the construction different fasteners must be used. Steel: Secure each center support bracket using (3) 5/16” x 1”
Block Construction: Attach perforated angle 18” long to center support bracket(s) using (2) 3/8” x
For 6” Springs: Attach DSB wall angle(s) to the spring pads. Fasten the spring plate to the wall angle bracket, as shown in FIG P.
NOTE: 1” GRADE 5 bolts are provided and must be used with the flat and locking washers, to fasten the spring plate to the DSB wall angle.
NOTE: Additional center support brackets are not required for coupler support.
Torsion spring assemblies:
Torsion spring assemblies can be of several configurations depending on door size and weight. Left or right hand spring(s) must be identified by the color of the winding cone (Refer to FIG N, O and P. Ensure that spring warning tags are securely wired to all stationary spring cones.
NOTE: All red winding cone springs will be on the left side and all black winding cone springs will be on the right side.
NOTE: All set screws on drums and winding cones are painted red.
Locate torsion shaft and lay it in front of door on garage floor. Assemble torsion shaft assembly components according to spring and torsion shaft type as shown in FIG N, O, and P.
For 2” or
For
Lift the torsion shaft assembly into place by placing one end of the shaft into the end bearing bracket followed by the other end. Make sure the torsion shaft assembly and it’s components are positioned properly with respect to the end and center support brackets, as shown in FIG N, O and P. The torsion shaft should be level and held in place by the end and center support bracket(s). Secure the spring stationary cone(s) (dead end) to the center support bracket(s) using 3/8” bolts and nuts. Keep spring warning tags clearly visible.
NOTE: The center support brackets require (2) fasteners in the lower slot and hole, then (1) fastener in the top slot.
