■ Position opener head so that rail is lined up with center

line of open door.

■ Line up hanger brackets (not provided) with ceiling joists

or framing to locate where brackets are to be fastened.

See Fig. 22.

■ Mark location for 5/16" lag screws (not provided), and

drill two 3/16" pilot holes.

■ Fasten hanger brackets to joists using lag screws.

■ If garage framing supports are not visible, attach a length

of perforated angle or a 2x4 to the ceiling, securing it to

the hidden joists with lag screws long enough to fasten

firmly to garage framing (extra hardware items not pro-

vided). Then, attach one end of hanger brackets to the

perforated angle or 2x4 mounted to ceiling. Attach other

end of hanger brackets to opener’s chassis angle iron. See

Fig. 23 for alternate mounting methods.

■ Once opener is securely fastened in position, remove

wood blocks and temporary supports and lower door.

Check door for proper operation and clearance by manu-

ally moving door to full open and closed position. If door

hits rail at any point, raise opener head slightly higher

and re-mount in position.

NOTE: To provide additional support for rails 13’ length and

longer, use optional support bracket. (Accessories p.28)

■ Measure the rail’s overall span. Bracket is located on 1/3rd

of the overall rail span from the door header bracket end.

See Fig. 24

■ Place support bracket over rail (close side) on a diagonal.

Make sure support securement clamps clear rail sides.

■ Secure bracket onto rail by twisting support bracket as

indicated in Fig. 24A.

■ Attach mounting strap (not provided) to support bracket

and secure by fastening it to the ceiling.
