How to Guide

INSTALLATION STEP 9
CONNECT DOOR ARM TO TROLLEY
Follow instructions which apply to your door type as illustrated below and on the
following page.
IMPORTANT: The groove on the straight door arm MUST face away from the curved
door arm (Figure 4).
SECTIONAL DOORS ONLY
1. Make sure garage door is fully closed. Pull the emergency release handle to
disconnect the outer trolley from the inner trolley. Slide the outer trolley back
(away from the pulley) about 8" (20 cm) as shown in Figures 1, 2 and 3.
2. Fasten straight door arm section to outer trolley with the 5/16"x1" clevis pin.
Secure the connection with a ring fastener (Figure 1).
3. Fasten curved section to the door bracket in the same way, using the
5/16"x1-1/4" clevis pin.
4. Bring arm sections together. Find two pairs of holes that line up and join
sections. Select holes as far apart as possible to increase door arm rigidity
(Figure 2).
Hole alignment alternative (Figure 3):
• If holes in curved arm are above holes in straight arm, disconnect straight
arm. Cut about 6" (15 cm) from the solid end. Reconnect to trolley with cut
end down as shown.
• Bring arm sections together.
• Find two pairs of holes that line up and join with bolts, lock washers and
nuts.
Pull the emergency release handle toward the opener at a 45° angle so that the trolley
release arm is horizontal. Trolley will re-engage automatically when opener is
operated during the adjustments.
