SECTIONAL DOOR

AND ONE-PIECEDOOR WITH TRACK

1.Close the door and mark the inside vertical centerline of the garage door.

2.Extend the line onto the header wall above the door.

You can fasten the header bracket within 4 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 (see page 14) 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 provided) to securely fasten the 2x4 to structural supports as shown here and on page 13.

3.Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall 2" above the high point, This height will provide travel clearance for the top edge of the door.
