Installation

STEP 1

Position and Install Header Bracket

Installation procedures are determined by garage door typeS. Follow only those instructions which refer to your door.

THE HEADER BRACKET MUST BE RIGIDLY FASTENED TO THE HEADER WALL. REINFORCE THE WALL

WITH A 2x4 IF NECESSARY. FAILURE TO COMPLY MAY RESULT IN IMPROPER OPERATION OF SAFETY REVERSE SYSTEM (SEE PAGE 18).

1.With the door closed, locate and mark the vertical

conterline of garage door. Extend line onto header wall above the door.

2.Locate height for header bracket by opening door to highest point Of travel as shown. Draw an intersecting horizontal line on header wall 2" above high point. This height provides travel clearance for top edge of door.

NOTE: When the headroom is not sufficient for 2" clearance, the bottom edge of bracket may be placed parallel to the high point of travel.

Door Clearance Brackets are designed for low headroom installations (page 4). They replace the top brackets end roUere on the garage door, thereby lowering the high point of door travel. Installation instructions are contained in the accessory carton.

3.Position bracket as shown (bottom edge of bracket on horizontal line end centered on the vertical line).

Mark either top and bottom or left and right bracket holes, Drill 3/16" pilot holes and fasten bracket.

1.Find the vertical centerline as described in 1. above.

2.Locate height for header bracket by opening door to highest point of travel as shown. Measure the distance from top of door to floor. Subtract actual height of door. Add 8" to the remainder. Refer to example below.

NOTE: If total number of inches exceeds the height available in your garage, use the maximum height

possible. On finished ceilings, do not position the bracket closer than 1/2" from ceiling.

3.Measuring from top of door, draw an intersecting horizontal line on the header wall at determined height.

Position the bottom edge of header bracket on the horizontal line, (>entering bracket on vertical line. Mark

either top and bottom or left and right holes. Drill 3/16" pilot holes and fasten the bracket with 5/16"xf-7/8" lag screws as shown above.

	EXAMPLE
Distance from top of door (at
highest	point of travel) to floor	92"
Actual	height of door	-88"
Remainder		4"
Add		+ 8"
Bracket height on header wall		=12"
(Measure UP from top of door
in closed position.)
