For detailed information see supplemental instructions “Removing an Existing Door/ Prepar-
ing the Opening”. These instructions are not supplied with the door, but are available at no
charge from Wayne-Dalton, A Division Of Overhead Door Corporation, P.O. Box 67, Mt. Hope,
OH., 44660, or at www.Wayne-Dalton.com.
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. The jambs should extend a minimum of 12” (305 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
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.
WEATHERSTRIPS (MAY NOT BE INCLUDED):
Depending on the size of your door, you may have to cut or trim the weatherstrips (if neces-
sary) to properly fit into the header and jambs.
NOTE: If nailing product at 40°F or below, pre-drilling is required.
NOTE: Do not permanently attach weatherstrips to the header and jambs at this time.
For Quick Install track: For the header, align the weatherstrip with the inside edge of the
header and temporarily secure it to the header with equally spaced nails. Starting at either
side of the jamb, fit the weatherstrip up tight against the temporarily attached weatherstrip in
the header and flush with the inside edge of the jamb. Temporarily secure the weatherstrip
with equally spaced nails. Repeat for other side. This will keep the bottom section from falling
out of the opening during installation. Equally space nails approximately 12” to 18” apart.
For other track systems: For the header, align the weatherstrip 1/8” to 1/4” inside the header
edge, and temporarily secure it to the header with equally spaced nails. Starting at either
side of the jamb, fit the weatherstrip up tight against the temporarily attached weatherstrip in
the header and 1/8” to 1/4” inside the jamb edge. Temporarily secure the weatherstrip with
equally spaced nails. Repeat for other side. This will keep the bottom section from falling out
of the opening during installation. Equally space nails approximately 12” to 18” apart.
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.
NOTE: 6” low headroom conversion kit is available for 12” radius only. Contact your local
Wayne-Dalton dealer.
Backroom requirement: Backroom is defined as the distance needed from the opening
back into the garage to allow the door to open fully.
*NOTE: For door heights from 10’1” to 14’0”, refer to your operator manufacture installation
instructions for appropriate depth into room.
