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
bearing 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. 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.
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 or equivalent. Do not use
lumber marked as spruce-pine-fir or SPf). The mounting surface
must be securely attached to the wall with four (4) 3/8” anchors for
masonry constructions or four (4) 5/16” x 4” lag screws for wood
construction.
NoTe: Drill a 3/16” pilot hole in the mounting surface to avoid
splitting the lumber. Do not attach the mounting surface with nails.
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, 3” (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.
weather Seal (may Not be included):
Cut or trim the weather seal (if necessary) to the header and jambs.
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 space 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.
