DOOR INSTALLATION
INSTRUCTIONS
Before installing your door, be certain that you have read and followed all of the instruc-
tions covered in the pre-installation section of this manual. Failure to do so may result in an
improperly installed door.
NOTE: Reference TDS 160 for general garage door terminology at www.dasma.com.
IMPORTANT: IF THE DOOR WILL BE EXPOSED TO A SIGNIFICANT AMOUNT OF ROAD SALT,
PAINT THE BARE GALVANIZED BOTTOM WEATHER STEEL RETAINER TO INHIBIT RUSTING.

Preparing Vertical Tracks
NOTE: If you have a wall angle track assembly, skip this step.
NOTE: Refer to Door Section Identification / Parts Breakdown Of Parts, to determine if you
have vertical tracks.
Vertical tracks may or may not have to be cut to the proper length, prior to installing.
IMPORTANT: VERTICAL TRACKS ARE NOT REQUIRED TO BE CUT DOWN IF YOU HAVE DOOR
HEIGHTS 7'-0" OR 8'-0".
Determine the radius of your horizontal track.

Refer to the vertical track cutting chart to determine the length needed to be cut off at the top
of the vertical tracks. Using this measurement, measure and cut the vertical track off at the
top, as shown. Remove any burrs from the cut edge of vertical track.

Now, two holes must be drilled into the top of the cut vertical track. Using the illustration
shown below, mark and drill the hole locations using a 5/16" drill bit. Once the holes have
been drilled, remove any burrs from the drilled holes. Repeat the same process for the other
vertical track.

Attaching Flag Angles and Jamb Brackets To
2
Vertical Tracks
Hand tighten the left hand flag angle to the left hand vertical track using (2) 1/4" - 20 x 5/8"
carriage bolts and (2) 1/4" - 20 flange hex nuts.
NOTE: The bottom jamb bracket is always the shortest bracket, while the center jamb
bracket is the next tallest. If three jamb brackets per side are included with your door, you will
have received a top jamb bracket, which is the tallest.
To attach the bottom jamb bracket, locate lower hole of the hole/ slot pattern of the 1st hole
set on the vertical track. Align the slot in the jamb bracket with the lower hole of the hole/ slot
pattern. Hand tighten jamb bracket using (1) 1/4" - 20 x 5/8" carriage bolt and (1) 1/4" - 20
flange hex nut.
Place the center jamb bracket over the lower hole of the hole/ slot pattern that is centered
between the bottom jamb bracket and flag angle of the 2nd hole set. Hand tighten jamb
bracket using (1) 1/4" - 20 x 5/8" carriage bolt and (1) 1/4" - 20 flange hex nut.
If a top jamb bracket was included, hand tighten it to vertical track using the lower hole of the
hole/ slot pattern in the 3rd hole set and (1) 1/4" - 20 x 5/8" carriage bolt and (1) 1/4" - 20
flange hex nut.

Attaching Bottom Corner Brackets
NOTE: Refer to door section identification, located in the pre-installation section of this
manual or refer to Breakdown Of Parts.
Uncoil the counterbalance lift cables. Depending on which bottom corner brackets you have,
either slip the loop at the ends of the counterbalance lift cable over the milford pin of the
bottom corner bracket or secure the cable loop to the clevis pin and bottom corner bracket
using a 5/16" flat washer and a cotter pin. Repeat for other bottom corner bracket.
WARNING
ENSURE TIGHT FIT OF CABLE LOOP OVER MILFORD PIN TO PREVENT
COUNTERBALANCE LIFT CABLE FROM COMING OFF THE PIN, WHICH
COULD ALLOW THE DOOR TO FALL AND RESULT IN SEVERE OR FATAL
INJURY.

and if applicable two more 1/4" - 20 x 11/16" self drilling screws. Repeat same process for
the right hand side.
IMPORTANT: THE 1/4" - 20 X 11/16" RED HEAD SELF DRILLING SCREWS MUST BE MUST
BE INSTALLED THROUGH THE HOLES OF THE BOTTOM CORNER BRACKETS, AS SHOWN.
Insert a short stem track roller with a roller spacer (if applicable) into the bottom corner
bracket. Repeat for other side.
NOTE: Verify bottom weather seal is aligned with bottom section. If there is more than 1/2"
excess weather seal on either side, trim weather seal even with bottom section.
