Adjusting Top Fixtures

NOTE:
Depending on your door, you may have Top Fixture Bases and Top Fixture Slides or
you may have Top Fixture Assemblies. Refer to Package Contents / Breakdown of Parts, to
determine which Top Fixtures you have.
With horizontal tracks installed, you can now adjust the top fixtures. Vertically align the top
section of the door with the lower sections. Once aligned, position the top fixture slide, out
against the horizontal track. Maintaining the slide’s position, tighten the (2) 1/4” - 20 flange
hex nuts or the (1) 5/16” - 18 hex nut to secure the top fixture slide to the top fixture base.
Repeat for other side.

INSTALLATION INSTRUCTIONS
Attaching Rear Back Hangs
16
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.
NOTE:
If an opener is installed, position horizontal tracks one hole above level when securing
them to the rear back hangs.
Perforated Angle Gauge Weight Limitations For Extension Springs:
Perforated Angle Gauge
Door Balance Weight
2” x 2” x 12 Gauge
Less Than 400 lbs.
1-1/4” x 1-1/4” x 13 Gauge
Less Than 175 lbs.
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.
WARNING
KEEP HORIZONTAL TRACKS PARALLEL AND WITHIN 3/4” TO 7/8” FROM
DOOR EDGE, OTHERWISE DOOR COULD FALL, RESULTING IN SEVERE OR
FATAL INJURY.
IMPORTANT:
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.
NOTE:
If rear back hangs are to be installed over drywall, use (2) 5/16” x 2” hex head lag
screws and make sure lag screws engage into solid structural lumber.
