STEP 4: BACKER BOARD INSTALLATION
Predrill backer board.
1. Clamp the track ② to the backer board ① , 1" above the bottom edge.
2. Predrill through the 3/8" holes using a 3/16" bit, through the
backer board.
Figure 13. Predrilling Backer Board
Positioning backer board on wall.
1. The backer board ① offset is referenced from the inner surface of
the opening that coincides with the closed position of the system.
The offset distance is based on the kit size/door width. Reference
Table 3 for the correct offset.
Kit Size Door Width (DW) Backer Board Offset
36" (72" track)
30" ≤ DW < 32 1/2" = 68 − (2*Door Width)
36" ≥ DW ≥ 32 1/2" 3"
42" (84" track)
36" ≤ DW < 38 1/2" = 80 − (2*Door Width)
42"≥ DW ≥ 38 1/2" 3"

Figure 15. Backer Board Stud Alignment
Predrill the backer board for stud attachment.
1. Using a stud nder, mark all stud locations on the wall that overlap
with the placement of the backer board ①.
2. Mark stud locations on backer board.
3. With the backer board held in position, and leveled, predrill for the
included wood screws using 1/8" bit (two screws per stud, evenly
spaced vertically on backer board. The 72" kit comes with mounting
hardware for 5 studs, the 84" kit comes with mounting hardware for
6 studs).
Note: After completing all predrilling of the backer board, sand/paint/
stain the board if desired.
4. Once the desired nish is achieved, fasten the backer board to the
wall with the included #9 x 2 1/2" at head screws ⑧.
Note: The floor below barn door must be level. If not, take opening
and backer board measurements from highest point.
Note: If installing into thick carpet, firmly press the tape measure
to the base of the carpet before making the backer board height
measurement.
