Installation Step 4

Position the Opener

Follow instructions which apply to your door type as illustrated.

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

If the top panel hits the trolley when you raise the door, pull down on the trolley release arm to disconnect the inner and outer sections. The trolley can remain disconnected until Step 12 is completed.
