ATTACHING END BRACKETS TO FLAG ANGLES
15
IMPORTANT: Warning tags must be securely attached to end bracket(s).
IMPORTANT: For single spring doors, ensure the left hand cable drum bearing is all the
way to the left and up against the flag angle. If the cable drum is pulled away from the flag
angle, then the idler bracket can rub against the cable drum causing noise.
NOTE: Drill 3/16” pilot holes into header for the lag screws.
STEP 15 INSTRUCTIONS
15a. Beginning with the right hand side, slide the end bracket (I4.) onto the winding shaft so
that the splines in the ratchet wheel fit onto the winding shaft grooves.
15b. Attach the end bracket to the flag angle (A1.) using (1) 5/16” - 18 x 3/4” carriage bolt,
(1) 5/16” washer and (1) 5/16” - 18 hex nut. Then secure the end bracket to the jamb using
(1) 5/16” x 1-5/8” lag screw.
NOTE: If ratchet wheel falls out of end bracket, refer to illustration for proper insertion
orientation.

17
STEP 17 INSTRUCTIONS
17a. With the door in the fully closed position, place locking pliers onto both vertical tracks
(H5.) (H6.) just above the third track roller (C1.). This is to prevent the garage door from
rising while winding spring(s).
NOTE: Check the following before attempting to wind the spring(s):
17b. Counterbalance lift cables are secured at bottom corner brackets.
17c. Counterbalance lift cables are routed unobstructed to cable drums.
17d. Counterbalance lift cables are correctly installed and wound onto cable lift drums.
17e. Spring tube is installed correctly.
17f. Review the Winding Spring Turn Chart in Step Winding Spring(s), to determine the
number of spring turns required.
NOTE: Door MUST be closed and locked when winding or making any adjustments to the
spring(s).
WARNING
FAILURE TO PLACE LOCKING PLIERS ONTO VERTICAL TRACK CAN
ALLOW DOOR TO RAISE AND CAUSE SEVERE OR FATAL INJURY.
