STEP 1
Position and Install Header Bracket
Installation procedures are determined by garage door typeS. Follow only those
instructions which refer to your door.
REVERSE SYSTEM (SEE PAGE 18).
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
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 Oftravel 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.

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.)
