INSTALLATION STEP 1

Determine the HeaderBracketLocation

To prevent possible SERIOUSINJURYor DEATH:

•Headerbracket MUST be RIGIDLYfastened to structural support on headerwall or ceiling, otherwise garagedoor might NOTreversewhen required. DONOTinstall header bracket over drywall.

•Concrete anchors MUST be used if mounting headerbracket or 2x4 into masonry.

•NEVERtry to loosen, move or adjust garagedoor, springs,

cables, pulleys, brackets, or their hardware,ALL of which are under EXTREMEtension.

•ALWAYScall a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced

garagedoor might NOT reversewhen required.

Installation procedures vary according to garagedoor types. Follow the instructions which apply to your door.

1.Closethe door and mark the inside vertical centerline of the garagedoor.

2.Extendthe line onto the headerwall above the door.

You can fasten the header bracketwithin 4 feet (1.22 m) of the left or right of the doorcenter only if a torsion springor center bearingplate is in the way; or you can attach it to the ceiling (see page 13) when clearance is minimal. (It may be mountedon the wall upsidedown if necessary,to gain approximately1/2" (1 cm))

If you needto install the headerbracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports as shown hereand on page13.

3.Openyour door to the highest point of travel as shown. Draw an intersecting horizontal line on the headerwall above the high point:

•2" (5 cm) above the high point for sectional door and one-piece door with track.

•8" (20 cm) above the high point for one-piece door without track.

This height will provide travel clearancefor the top edgeof the door.

NOTE:If the total number of inches exceedsthe height available in your garage, use the maximum height possible, or refer to page 13 for ceiling installation.
