Bracket
To avoid installation difficulties, do
not run the garage door opener until
instructed to do so.
1. Place the 3 T-rail sections on a flat
surface for assembly. The end
sections are identical. Make sure the
"arrow label" on the center 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 pulley bracket on the front end of
the T-rail as shown. Fasten securely with the
hardware provided.
NOTE: When tightening the bolts be sure to keep
bracket parallel to the rail. Otherwise, the rail may
bow when the opener is operated.
