ASSEMBLY STEP 1
For Sectional and
One-Piece Doors ONLY
Assemble the T-Rail and
Attach the Chain Pulley 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. The center
section must be positioned with the
braces against the end sections as
shown. Make sure the "directional
arrow" on the center section is
pointing toward the front (to door).
Study the illustration carefully.
2. Bolt rail sections together with the
hardware illustrated and from the
direction indicated. (When assembled,
T-rail has a front-to-back position 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. 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.
