Step 3: Attach Unit to Front Wall Bracket 
Raise the front end of the opener and attach 
it to the front wall bracket, using the ¼” x 4” 
hex head bolt and the supplied ¼” plastic 
insert nut. Take care not to over tighten nut; 
tighten only until end of bolt is flush with out-
side of nut. 
NOTE: If you have a torsion spring 
counter-balance system, it will be 
necessary to raise the motor Head 
Assembly of the opener and support it 
on a step-ladder to attach the front end 
of the opener to Wall Bracket. 
Step 4: Positioning the Motor End of Operator 
CAUTION: To prevent damage to steel, aluminum, fiberglass or glass panel doors do not rest the opener of the 
door without using a 2” x 4” at least 12” long.
Raise the motor end of the opener and support it 
so you can open the door to its fully open position. 
You may need help raising motor end if ladder is 
not high enough. 
Open the door and place a 2” x 4” piece of wood 
along the top section of the garage door. Rest the 
double rails on the 2” x 4”, as illustrated. 
Support the top section of the door to prevent 
sagging. 
Step 5: Mounting Motor End of Opener 
Align the center of opener tracks with 
the center line previously marked on 
the top section of the garage door to 
ensure rail will be parallel with the di-
rection of door travel. 
Use perforated hangers (cut as 
needed to adjust length) from ceiling 
or beams to hang opener at motor end 
(be sure to locate and mount to solid 
structural beams, as illustrated). 
Pre-drill with 3/16” drill bit and use 1/4” 
x 1-1/2” lag screws to ensure a rigid 
mount. Attach opener to hangers. 
WARNING: Do not use gear cap 
bolt or nut for hanger attachment, 
this may cause sprocket and 
chain misalignment, resulting in 
damage or possible injury! 
Note: Hanging brackets should be at an angle to provide rigid support. If hangers have no angle or if you use 
long hangers, cross brace the hangers to eliminate the possibility of sway during operation of the opener.
