Drill 3/16" pilot holes at each lag screw location. Fasten flag bracket to
jamb using (3) 5/16" × 1-5/8" lag screws, one in each of top, middle and
bottom holes. Repeat on opposite side.
Once flag brackets are securely fastened to jamb, tighten track bolts and
flange nuts connecting flag brackets to tracks (Fig. 11-D).
NOTE: The tops of vertical tracks must be level with each other. Check
this by measuring from top of door sections to top of track on both
sides. If they are not equal, cut material off bottom of one track to
lower it or raise other track.
NOTE: Pressure-treated lumber purchased after January 2004 is
treated with chemicals that have highly corrosive effects on metal
fasteners. Fasteners provided with door are intended for use with
standard lumber (not pressure-treated) only. If installing door
into an opening framed with pressure-treated lumber, it is highly
recommended that 5/16" × 1-5/8" lag screws with a minimum
galvanization equivalent of G185 be purchased for this application.
Step 11-4: Assemble Flag Brackets to Vertical Track
NOTE: On some doors this angle may be 82" long and will require (3)
additional fasteners per side. If angle has been preassembled, skip
STEP 11-4 and proceed with STEP 11-5.
Fasten horizontal angle to horizontal (curved) track using
(2) 1/4" × 5/8" track bolts and (2) 1/4" flange nuts.
Head of bolt faces inside track (Fig.11-E).
Step 11-5: Support Rear End of Track
Temporarily support rear end of track with a rope tied to trusses overhead
in garage or resting on tall ladder (Fig. 11-F).
Step 11-6: Assemble Horizontal Track to Flag Bracket
Place curved end of horizontal track over roller in top bracket.
Attach track to flag bracket using (2) 1/4" × 5/8" track bolts and
(2) 1/4" flange nuts. Head of bolt faces inside track.
NOTE: Horizontal and vertical track must join together to form a
continuous channel for rollers.
Attach end of horizontal angle to top of flag bracket with a
3/8" × 3/4" carriage bolt and 3/8" hex nut (Fig. 11-G).
For 15" radius track use top set of slots
For 12" radius track use middle set of slots
For low headroom track use bottom set of slots
Step 11-7: Assemble Rear Track Hangers
NOTE: Rear track hangers are not provided with standard hardware
and will need to be made at this time. They are used to attach rear
horizontal track to ceiling joist and must be strong enough to hold full
weight of door.
! WARNING
Sway braces must be used to prevent tracks from spreading and allowing
door to fall, which could cause serious injury. Bolts placed in end of each
track (Fig. 11-H) must be at least 1" long to prevent top section from
exiting track.
