 Hold the rail assembly above the power head with arrow
pointing toward the front of the power head and the
garage door.
 Rotate the rail assembly until the opening in the rail is
aligned with the sprocket.
 Lower the end rail onto the sprocket with the channel
(open end) facing down. Slowly rotate the rail to the
correct orientation as you lower it into position.
 When installed correctly, the teeth on the sprocket should
engage the rail assembly and the rail should sit flat on the
power head.
 Place the brackets on top of the studs, and over the end
rail.
 Place nuts onto the studs and tighten using a 10 mm
socket. Do not overtighten.
