IMPORTANT! WARNING TAGS MUST BE
SECURELY ATTACHED TO BOTH END
BRACKETS.
End brackets are right and left hand. You
can identify the right hand end bracket by
the disconnect cable guide hole in the top
of the bracket.
Beginning with either side, slide the end
bracket onto the winding shaft so that the
grooves in the ratchet wheel fit onto the
winding shaft splines.
Secure end bracket to the flag angle using
(1) 5/16”-18 x 3/4” carriage bolt,3/4”
washer and hex nut; then secure to the
jamb with 5/16” x 1-5/8” hex head lag
screw.
Repeat for other end bracket.
NOTE: No ratchet wheel is required on the
left hand side for single spring applications.
Only an end bracket is needed.
After completing this step, continue with
Step 4 on page 12.
