ASSEMBLY STEP 1
For Sectional and
One-Piece Doors ONLY
Assemble the 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 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, rail has a front-to-back position as
shown.)
NOTE: If 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 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.
