Attaching Rear Back Hangs
21
IMPORTANT:
HOLD THE DOOR DOWN TO PREVENT IT FROM RISING UNEXPECTEDLY IN THE
EVENT THE SPRING(S) WERE OVER-WOUND AND CAUTIOUSLY REMOVE LOCKING PLIERS
FROM VERTICAL TRACKS.
Raise the door until the top section and half of the next section are in the horizontal track
radius. Do not raise door any further since rear of horizontal tracks are not yet supported.
WARNING
RAISING DOOR INTO THE LOOSE HORIZONTAL TRACKS CAN RESULT IN
DOOR FALLING AND CAUSE SEVERE OR FATAL INJURY.
Clamp a pair of locking pliers onto the vertical tracks just above the second track roller on
one side, and just below the second track roller on the other side. This will prevent the door
from raising or lowering while installing the rear back hangs.
Using the chart below, select the appropriate perforated angle (may not be supplied). Fabri-
cate and install rear back hangs, as shown.

MAXIMUM OF DOOR EDGE, OTHERWISE DOOR COULD FALL, RESULTING
IN SEVERE OR FATAL INJURY.
WARNING
MAKE SURE BACK HANGS ARE BRACED SUFFICIENTLY TO RESIST ANY
MOTION DURING SPRING APPLICATION AND DOOR TRAVEL. IF BACK
HANGS PIVOT OR DEFLECT, ADD REINFORCEMENT UNTIL THEY REMAIN
FIRM AND STATIONARY. ANY BACK HANG THAT HAS BENT MUST BE
REPLACED.

DO NOT SUPPORT THE WEIGHT OF THE DOOR ON ANY PART OF THE REAR
BACK HANGS THAT CANTILEVERS 4” OR MORE BEYOND A SOUND FRAMING MEMBER.
