Installation Step 4

Position the Opener

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

• Raise the opener onto a stepladder.

CAUTION

To prevent damage to steel, aluminum, fiberglass or glass panel doors, do not rest the opener on the door without using a 2x4.

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.
