INSTALLATION STEP 1

Determine the Header Bracket Location

To prevent possible SERIOUSINJURYor DEATH:

•Header bracket MUST be RIGIDLYfastened to structural support on headerwall or ceiling, otherwise garagedoor might not reversewhen required. DO NOT install header bracket over drywall.

•Concrete anchors MUST be used if mounting header bracket 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 garagedoor binds, sticks, or is out of balance. An unbalanced garagedoor might not reversewhen required.

Installation procedures vary according to garage door

types• Follow the instructions which apply to your door.

SECTIONAL DOOR

AND ONE-PIECE DOOR WITH TRACK

1.Close the door and mark the inside vertical centerline of the garage door.

2.Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 feet of the left or right of the door center only if a torsion spring or center bearing plate is in the way; or you can attach it to the ceiling (see page 14) when clearance is minimal. (It may be mounted on the wall upside down if necessary, to gain approximately 1/2".)

If you need to install the header bracket on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural supports as shown here and on page 13.

3.Open your door to the highest point of travel as shown• Draw an intersecting horizontal line on the header wall 2" above the high point• This height will provide travel clearance for the top edge of the door.

NOTE: Door clearance brackets are available for sectional doors when headroom clearance is less than 2"• See accessory page 39.
