Follow instructions which apply to your door type as 
illustrated below and on the following page.

•  

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.

 – 

 

Fasten straight door arm section to outer trolley with 
the 5/16"x1" clevis pin. Secure the connection with a 
ring fastener.

 – 

 

Fasten curved section to the door bracket in the same 
way, using the 5/16"x1-1/4" clevis pin.

 – 

 

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.

 – 

 

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. 
Proceed to Adjustment Step 1, page 27. Trolley will 
re-engage automatically when opener is operated.
