Header bracket must be fastened to garage framing. Do NOT fasten to drywall, particle board, plaster or other such materials.

1.Finding header bracket mounting location.

•Close garage door.

–Use a pencil and level.

(Fig. 2-1, c).

–Make your mark across vertical line made earlier.

•Add 2-1/2" to height mark just made on wall. This is location for header bracket (Fig. 2-1, d).

Door springs are under high tension. If spring or its shaft is in the way, measure 2-1/2" above spring or shaft on the garage door centerline and mark this height as your location for header bracket.
