SECTIONAL DOOR ONLY

A 2x4 laid flat is convenient for setting an ideal door-to-rail distance.

•Raise the opener onto a stepladder. You will need help at this point if the ladder is not tall enough.

•Open the door all the way and place a 2x4 laid flat on the top section beneath the rail.

INSTALLATION STEP 5

Hang the Opener

Two representative installations are shown. Yours may be different. Hanging brackets should be angled (Figure 1) to provide rigid support. On finished ceilings (Figure 2), attach a sturdy metal bracket to structural supports before installing the opener. This bracket and fastening hardware are not provided.

1.Measure the distance from each side of the motor unit to the structural support.

2.Cut both pieces of the hanging bracket to required lengths.

3.Drill 3/16" pilot holes in the structural supports.

4.Attach one end of each bracket to a support with 5/16"-18x1-7/8" lag screws.

5.Fasten the opener to the hanging brackets with 5/16"-18x7/8" hex bolts, lock washers and nuts.

6.Check to make sure the rail is centered over the door (or in line with the header bracket if the bracket is not centered above the door).

7.Remove the 2x4. Operate the door manually. If the door hits the rail, raise the header bracket.

8.Grease the top and underside of the rail surface where the trolley slides with rail grease.
