NOTE:
Cable drum assemblies are marked right and left hand. Cable drums and TorqueMas-
ter

spring tube assembly are cam shaped to fit together only one way.
Starting on the right hand side, pre-wrap the cable drum with the counterbalance lift cable
1/2 wrap, as shown. Position the TorqueMaster
®
spring tube assembly so the cam peak
is pointing straight up. Slide the cable drum over the winding shaft until the cable drum
seats against the TorqueMaster
®
spring tube assembly. The winding shaft must extend past
the cable drum far enough to expose the splines and the grooves. Align the winding shaft
grooves with the round notch in the flag angle.

Insert the idler bracket into the left hand cable drum.
Lightly press the idler bracket into the cable drum until two distinct clicks are heard, or the
bracket is inserted all the way.
IMPORTANT:
ENSURE THE SNAPS ON THE IDLER BRACKET (LEFT HAND SIDE) ARE EN-
GAGED INTO THE LEFT HAND CABLE DRUM, SO THAT IT DOES NOT COME BACK OUT.
NOTE:
The idler bracket is designed for permanent assembly. Do not attempt to remove idler
bracket once inserted into the cable drum.
NOTE:
The idler bracket must extend past the cable drum far enough to expose the groove.
Align the idler bracket groove with the round notch in the flag angle.

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.
Beginning with the right hand side, slide the end bracket onto the winding shaft so that the
splines in the ratchet wheel fit onto the winding shaft grooves. Attach the end bracket to the
flag angle 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.
FOR DOUBLE SPRING APPLICATIONS:
Repeat same process for left hand end bracket.
