■
Use 1-1/4" × 1-1/4" punched angle, at least 13 gauge or 3/32" steel to
make two rear track hangers with sway braces (Fig. 11-H).
■
Attach to track using at least 1" long bolts (Fig. 11-H).
Step 11-8: Placement of Rear Track Hangers
Placement of rear track hangers is critical for door to operate properly. They
should not be mounted any farther than 6" from end of horizontal track and
should hold horizontal track level and square to door.
■
Squareness should be measured by comparing two diagonal distances
(Fig. 11-I):
1) From top left-hand corner of door to rear of right-hand
horizontal track.
2) From top right-hand corner of door to rear of left-hand
horizontal track.
■
Squareness distances should be within 1/2" of each other. Horizontal
track can be out of level up to 1" from front jamb to rear track hanger
(Fig. 11-I).
■
With track square and level with opening, track hangers can be fastened
permanently to ceiling trusses using (3) 5/16" × 1-1/2" lag screws. Drill
3/16" pilot holes before installing 5/16" lag screws.
! WARNING
To prevent door from falling and causing serious injury, be sure rear track
hangers are properly secured to trusses with adequate length screws.
Step 11-9: Adjust Top Section
■
With track installed, top door section can now be properly adjusted.
■
Loosen slide on top bracket and push top of door against stop molding or
door jamb. Pull roller toward you so it is tight against the groove in track.
■
Tighten slide bolts (Fig. 11-J).
■
Remove all 10d 3" nails holding all sections in place.
