Wayne-Dalton 346918 Top Section, Horizontal Tracks/Q.I. Flag Angles, End Bearing Brackets

Place the top section in the opening. Temporarily secure the top section by driving a nail into the header near the center of the door and bending it over the top section. Now, flip up the graduated end and center hinge leaves, hold tight against section, and fasten center hinges first and end hinges last (refer to step, Stacking Sections). Vertical track alignment is critical. Position flag angle between 1-11/16” (43 mm) to 1-3/4” (44 mm) from the edge of the door; tighten the bottom lag screw. Flag angles must be parallel to the door sections. Repeat same process for other side.

Important: the dimension between the flag angles must be door width plus 3-3/8” (86mm) to 3-1/2” (89 mm) for smooth, safe door operation.

For Quick Install Track:

Complete the vertical track installation by securing the jamb bracket(s) and tightening the other lag screws. Repeat for other side.

For Fully Adjustable track:

Complete the vertical track installation by securing the jamb bracket(s) and tightening the other lag screws. Push the vertical track against the track rollers so that the track rollers are touching the deepest part of the curved side of the track; tighten all the track bolts and nuts. Repeat for other side.

Note: If you have Quick Install flag angles, complete this step.

To install horizontal track, place the curved end over the top track roller of the top section. Align key slot of the horizontal track with the Quick Install tab of the flag angle. Push curved portion of horizontal track down to lock in place.

WARNING

Do not raise door until horizontal tracks are secured at rear, as outlined in Step, Rear Back Hangs, or door could fall from overhead position causing severe or fatal injury.

Level the horizontal track assembly and bolt the horizontal track angle to the first encoun- tered slot in the flag angle using (1) 3/8”-16 x 3/4” truss head bolt and (1) 3/8”-16 hex nut. Repeat for other side.

Remove the nail that was temporarily holding the top section in place, installed in step, Top Section.

Important: Failure to remove nail before attempting to raise door could cause permanent damage to top section.

Note: If an idrive® opener will be installed, position horizontal tracks slightly above level.

Note: If you have Fully Adjustable flag angles, complete this step.

To install horizontal track, place the curved end over the top track roller of the top section. Align the bottom of the horizontal track with the top of the vertical track. If you have Quick Install horizontal track, tighten the horizontal track to the flag angle with a stud plate and (2) 1/4”-20 flange hex nuts. If you have Universal horizontal track, tighten the horizontal track to the flag angle with (2) 1/4”-20 x 9/16” track bolts and (2) 1/4”-20 flange hex nuts.

With horizontal tracks installed, you can now adjust the top fixtures. Vertically align the top section of the door with the lower sections. Once aligned, position the top fixture slide, out against the horizontal track. Maintaining the slide’s position, tighten the (2) 1/4”-20 flange hex nuts to secure the top fixture slide to the top fixture base. Repeat for other side.
