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.
