installation Step 1

Determine Header Bracket Location

Installation procedures vary according to

garage door types. Follow the instructions which apply to your door.

If the header bracket is not rigidly fastened to

a structural support on the header wall or

ceiling, the safety reverse system may not work properly (see page 30). The door might

not reverse when required, and could cause

serious injury or death.

The garage door springs, cables, pulleys, brackets and their hardware are under extreme

tension. Do not attempt to loosen, move or adjust them yourself. Serious personal injury or death could result. Call for professional

2x4

StructuraI	• Close the door and mark the inside
	vertical centerline of the garage door.
	• Extend the line onto the header wall
	above the door.
	Remember, you can fasten the
	header bracket within 2 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 (refer to 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 supplied) to securely fasten
	the 2x4 to structural supports as shown
	here and on page 13.

•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.

Door clearance brackets are available for sectional doors when headroom clearance is less than 2". See accessory page 38.
