NOTE: Rail comes fully preassembled with straight door arm already attached.

Unpack one-piece preassembled rail.

Leave straight door arm taped inside rail for safe and convenient installation—it will be untaped and used later.

Position door opener head with control panel facing front of garage. Rest opener head on cardboard or protective surface on floor so opener does not get scratched. Chassis side of opener (with motor shaft sticking out) facing up.

Position rail onto opener chassis by lining up rail sprocket opening with motor head shaft (Fig. 17A). Make sure shaft engages teeth inside rail sprocket. Press rail down firmly onto shaft and opener chassis. DO NOT HAMMER.

Position 2 "C" brackets over rail and onto chassis. Flanges on "C" brackets must fit into cutout area on chassis (Fig. 17B).

Insert screws 6 x 14 through bracket holes and into chassis holes, and tighten screws firmly to hold rail to head (Fig. 17C).

For sectional doors, proceed to step 8-5.

ADDITIONAL STEP FOR ONE-PIECE DOORS ONLY:

IMPORTANT NOTE: For installation on One-Piece Doors only, the straight door arm that is factory installed onto the rail must be replaced by the curved door arm supplied as part of hardware in powerhead box. This must be done after attaching rail to powerhead, before moving to step 8-5.

Turn rail and opener head over so that open channel in rail faces up.

Untape straight door arm that is secured inside rail.

Remove and save the two phillips head screws that are securing the door arm pin and straight door arm (Fig. 18).

Lift arm and pin straight out of slot in trolley, and remove pin from straight door arm.

Insert pin into short side of curved door arm as shown.

Orient arm so that long side extends away from trolley.

Carefully insert pin and door arm into slot in trolley.

Push pin into slot with door arm so pin is fully seated into trolley slot. IMPORTANT: Pin must be straight and seated properly into recessed area in trolley. See Fig. 18A.

Secure pin and curved arm with the two phillips screws which were removed from trolley—DO NOT use any other screws. Tighten screws firmly.

Turn rail and powerhead over so that open channel in rail faces down. Now proceed to Step 8-5.
