INSTALLATION STEP 5

Hang the Opener

Three representative installations are shown. Yours may

be different. Hanging brackets should be angled (Figure 1)

to provide rigid support. On finished ceilings (Figure 2 and

Figure 3), attach a sturdy metal bracket to structural

supports before installing the opener. This bracket and

fastening hardware are not provided.

1. Measure the distance from each side of the motor unit

to the structural support.

2. Cut both pieces of the hanging bracket to required

lengths.

3. Drill 3/16" pilot holes in the structural supports.

4. Attach one end of each bracket to a support with

5/16"-18x1-7/8" lag screws.

5. Fasten the opener to the hanging brackets with

5/16"-18x7/8" hex bolts, lock washers and nuts.

6. Check to make sure the rail is centered over the door

(or in line with the header bracket if the bracket is not

centered above the door).

7. Remove the 2x4. Operate the door manually. If the door

hits the rail, raise the header bracket.

NOTE: DO NOT connect power to opener at this time.

To avoid possible SERIOUS INJURY from a falling garage door

opener, fasten it SECURELY to structural supports of the

garage. Concrete anchors MUST be used if installing any

brackets into masonry.
