Preparing the Opening
IMPORTANT: IF YOU JUST REMOVED YOUR ExISTING DOOR OR YOU ARE INSTALLING A
NEW DOOR, COMPLETE ALL STEPS IN PREPARING THE OPENING.
To ensure secure mounting of track brackets, side and center brackets, or steel angles to
new or retro-fit construction, it is recommended to follow the procedures outlined in DASMA
technical data sheets #156, #161 and #164 at www.dasma.com.
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. 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
attached 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.
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. Equally space
nails approximately 12" to 18" apart.
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, 2-1/2" (64 mm) of additional headroom is required.
Backroom requirement: Backroom is defined as the distance needed from the opening
back into the garage to allow the door to open fully.
