When installing your door you must use sections of the appropriate height in the right stacking order. What sections heights you need to use in what order depends on the height of your door.

Unless your door is six sections in height, you will not receive an Intermediate III section.

The bottom section can be identified by the factory attached bottom astragal and by the bottom bracket warning labels on each end stile.

The intermediate I section may have a warning label attached to either right or left hand end stile of the section. This section is always the 3rd section from the bottom of the door.

The inside perimeter of your garage door opening should be framed with wood jamb and header material. The jambs and header must be securely fastened to sound framing members. It is recommended that 2” x 6” lumber be used. The jambs must be plumb and the header level. The jambs should extend a minimum of 14” (357 mm) above the top of the opening for Torsion counterbalance systems. For low headroom applications, the jambs should extend to the ceiling height. Minimum side clearance required, from the opening to the wall, is 3-1/2” (89 mm).

Important: Closely inspect jambs, header and mounting surface. Any wood found not to be sound, must be replaced.

For Torsion counterbalance systems, a suitable mounting surface (2” x 6”) must be firmly at- tached to the wall, above the header at the center of the opening.

Note: Drill a 3/16” pilot hole in the mounting surface to avoid splitting the lumber. Do not attach the mounting surface with nails.

Weather seal (may not be included):

Cut or trim the weather seal (if necessary) to the header and jambs. Note: If nailing product at 40°F or below, pre-drilling is required.

For Q.I. track: Align the header seal with the inside edge of the header and temporarily secure it to the header with equally spaced nails. Next, fit the jamb seals up tight against the header seal and flush with the inside edge of the jamb. Temporarily secure the jamb seals with equally spaced nails. This will keep the bottom section from falling out of the opening during installation.

For F.A. track: Align the header seal 1/8” to 1/4” inside the header, and temporarily secure it to the header with equally spaced nails. Next, fit the jamb seals up tight against the header seal and 1/8” to 1/4” inside the jamb. Temporarily secure the jamb seals with equally spaced nails. This will keep the bottom section from falling out of the opening during installation.

Note: Do not permanently attach weather seal to the jamb at this time.

Headroom requirement: Headroom is defined as the space needed above the top of the door for tracks, springs, etc. to allow the door to open properly. If the door is to be motor operated,
