To avoid installation difficulties, do not run the garage door

section is pointing in the direction shown in the
illustration.
2. Connect the center section and the 1/4" lock
nuts to the end sections from the same side, as
shown.
NOTE: If T-rail is not assembled exactly as
shown, trolley will not travel smoothly along
length of rail or it will hit against nuts.
3. Insert the carriage bolts from the opposite side of the end
sections. Tighten the nuts. When assembled, T-rail has a
front-to-back position as shown.
4. Position the chain sprocket bracket on the front end of the
T-rail as shown. Fasten securely with the hardware provided.
