•Align the holes in the back section of the T-rail with the holes in the motor unit.

•Fasten the rail with the two washered screws previously removed. Tighten securely. Remember to use only these screws! Any other screws will cause serious damage to the opener.

•Insert a 5/16"-18x7/8" hex screw into the cover protection bolt hole in the T-rail as shown. Tighten securely with a 5/16" lock washer and nut.
