STEP 2 Fasten the rail to the motor unit
To avoid SERIOUS damage to garage door opener, use ONLY those bolts/fasteners mounted in the
top of the opener.
1. Insert a 1/4"-20x1-3/4" bolt into the cover protection bolt hole on the back end of the rail as
shown. Tighten securely with a 1/4"-20 lock nut. DO NOT overtighten.
2. Remove the bolt and nut from the top of the motor unit.
3. Use the carton to support the front end of the rail.
4. Place the “U” bracket, flat side down onto the motor unit and align the bracket holes with the bolt
holes.
5. Fasten the “U” bracket with the previously removed bolt and lock nut; DO NOT use any power
tools. The use of power tools may permanently damage the garage door opener.
