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” (356 mm) above the top of the opening for Torsion spring applications. For low headroom applications, the jambs should extend to the ceiling height. Minimum side clearance required, from the opening to the wall, is
IMPORTANT: Closely inspect existing jambs, header and mounting surface. Any wood found not to be sound, must be replaced.
For torsion spring applications, a suitable mounting surface must be firmly attached to the wall, above the header at the center of the opening. The mounting surface must be 2” x 6” lumber minimum (Select southern yellow pine lumber. Do not use lumber marked as
NOTE: Drill 3/16” pilot holes in the mounting surface to avoid splitting the lumber. Do not attach the mounting surface with nails.
Weather Seal (May Not Be Included):
Cut the weather seal (if necessary) to fit the header and jambs.
Align the header seal 1/8” to 1/4” inside the header and temporarily attach 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 attach the jamb seals with equally spaced nails approximately 12” to 18” apart. 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.
