applications, repeat the same process for the other side.
REMOVE SPRING TENSION:
To remove spring tension, place a regular 5/8” wrench onto the
winding shaft. Place pawl knob in upper position.
IMPORTANT:
BE PREPARED TO HOLD THE FULL TENSION OF THE SPRING.
Pull down on the wrench to relieve pressure between the pawl and the ratchet wheel. Push in
on the pawl to allow the three ratchet wheel teeth to pass by the pawl, as you carefully allow
the wrench to be rotated upward by the spring tension, release the pawl to allow it to engage
with the ratchet wheel. Place pawl knob in lower position. For double spring applications,
repeat the same process for the other side.
IMPORTANT:
DO NOT ADD OR REMOVE MORE THAN 1 SPRING TURN (1 SPRING TURN
EQUALS 10 TEETH ON RATCHET WHEEL) FROM THE RECOMMENDED NUMBER OF TURNS
SHOWN ON THE WINDING SPRING TURN CHART.
If the door still does not operate easily, lower the door into the closed position, unwind
spring(s) completely, and recheck the following items:
1.) Is the door level?
2.) Are the TorqueMaster
®
spring tube and flag angles level and plumb?
3.) Does the distance between the flag angles equal door width plus 3-3/8” to 3-1/2”?
4.) Do the counterbalance lift cables have equal tension? Adjust if necessary.
5.) Rewind the spring(s).
6.) Make sure door is not rubbing on jambs.

Attaching End Bearing Brackets
Tools Required: Power drill, 3/16” Drill bit, Ratchet wrench, 7/16” Socket driver,
9/16” Socket, 9/16” Wrench, Tape measure, Step ladder, Safety glasses, Leather

B1
NOTE:
Prior to fastening end bearing brackets into the door jamb, pilot drill using a 3/16”
drill bit.
IMPORTANT:
RIGHT AND LEFT HAND IS ALWAYS DETERMINED FROM INSIDE THE BUILDING
LOOKING OUT.
NOTE:
Depending on your door’s configuration you may have to break the end bearing
brackets apart.
NOTE:
End bearing brackets are right and left hand.
IMPORTANT:
THE END BEARING BRACKET’S LOWER SLOTS ARE USED ON DOORS WITH
12” RADIUS TRACK; THE UPPER SLOTS ARE USED ON DOORS WITH 15” RADIUS TRACK.

B2
NOTE:
Prior to fastening center bracket(s) to the header, pilot drill using a 3/16” drill bit.
NOTE:
On some single spring doors, the spring can be longer than half the opening width. If
your spring is longer, then the center bracket must be mounted off center for the spring to fit
properly. Measure spring length adding room for spring growth during winding, to determine
appropriate center bracket location.
IMPORTANT:
USE A 5/16” X 2-1/2” RED HEAD LAG SCREW INSTEAD OF THE 5/16” X
1-5/8” RED HEAD LAG SCREW IF MOUNTING SURFACE IS COVERED BY DRYWALL. THE LAG
SCREW MUST BE ATTACHED THROUGH THE BOTTOM HOLE OF THE CENTER BRACKET(S).
IF MOUNTING SURFACE IS A 2” X 6” BOARD INSTALLED ON TOP OF MASONRY, DRILL A
CLEARANCE HOLE IN MASONRY FOR THE 5/16” X 2-1/2” RED HEAD LAG SCREWS.
