20	Securing Door for Spring Winding(s)
	Tools: Vice Clamps

With the door in the fully closed position, place vice clamps onto both vertical tracks just above the third track roller. This is to prevent the garage door from rising while winding springs.

WARNING

Failure to place vice clamps onto vertical track can allow door to raise and cause severe or fatal injury.

22	Rear Back Hangs
	Tools: Ratchet wrench, Socket: 1/2” 5/8”, Wrench: 1/2” 5/8”, (2) Vice

Important: Hold the door down to prevent it from rising unexpectedly in the event the spring(s) was over-wound and cautiously remove vice clamps 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 further can result in door falling and cause severe or fatal injury.

Vice clamps above third track roller on both sides of door

Vice clamps attached to inner and outer rail of vertical track

Bottom section

Clamp a pair of vice clamps 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 perforated angle (may not be supplied), (2) 5/16” x 1-5/8” hex head lag screws and

(3)5/16” bolts with nuts (may not be supplied), fabricate rear back hangs for the horizontal tracks. Attach the horizontal tracks to the rear back hangs with 5/16”-18 x 1 hex bolts and nuts (may not be supplied).

NOTE: Doors heights over 8’0” or door widths over 11’0”, require an additional set of rear center back hangs to be installed and located at the middle of the horizontal tracks, see parts breakdown.

Using perforated angle (may not be supplied), (2) 5/16” x 1-5/8” hex head lag screws and (3) 5/16” bolts with nuts (may not be supplied), fabricate rear center back hangs for the horizon- tal tracks. Measure and drill a 3/8” diameter hole through the center length of the horizontal track, as shown. Attach the rear center back hangs to the horizontal tracks with (1) 3/8” Truss head bolt and (1) 3/8” nut (may not be supplied).

WARNING

Keep horizontal tracks parallel and within 3/4” to 7/8” maxi- mum of door edge, otherwise door could fall, resulting in

21	Winding Springs
	Tools: Step Ladder, Approved winding bars, 3/8” Wrench

Position a ladder slightly to the side of the spring so that the winding cone is easily acces- sible, and so your body is not directly in line with the winding bars.

IMPORTANT: Check the warning tag(s) attached to the spring(s) for the re- quired number of complete turns, to balance your door.

WARNING

Prior to winding or making adjustments to the springs, ensure you’re winding in the proper direction as stated in the Instal- lation Instructions. Otherwise the spring fittings may release from spring if not wound in the proper direction and could result in severe or fatal injury.

Alternately inserting the winding rods into the holes of the springs winding cone, rotate the winding cone upward toward the ceiling, 1/4 turn at a time, until the required number of complete turns for your door height is achieved. As the last 1/8 to 1/4 turn is achieved, securely hold the winding rod while tightening both set screws in the winding cone to 14-15 ft. lbs. of torque (once set screws contact the torsion shaft, tighten screws one full turn).

Carefully remove winding rod from winding cone. Repeat for the opposite spring. While holding the door down to prevent it from raising unexpectedly in the event the spring(s) were

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.

Note: 26” angle must be attached to sound framing members and nails should not be used.

Now, permanently attach the weatherstrips on both door jambs and header. The weather- strips were temporarily attached in Preparing the Opening, in the pre-installation section of this manual.

NOTE: When permanently attaching the weatherstrips to the jambs, avoid pushing the weath- erstrips too tightly against the face of door.

WARNING

Prior to winding or making adjustments to the springs, ensure you’re winding in the proper direction as stated in the Instal- lation Instructions. Otherwise the spring fittings may release from spring if not wound in the proper direction and could result in severe or fatal injury.

Now, lift door and check its balance. Adjustments to the required number of spring turns stated may be necessary. If door rises off floor under spring tension alone, reduce spring
