Installation Step 1

Determine Header Bracket Location

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

SECTIONAL Door or

ONE PIECE Door with Track

W ARN ING

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

26). 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 garage door service.

Guideline

•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 10) 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 9.

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