STEP 8
Stretch and Align the System
This step can be avoided or reduced if care is taken
to align and space the bulkheads properly during
assembly.
Attach a pair of chains or straps to the Front
Bulkhead assembly. Using a truck or other tow
vehicle, pull the system forward to fully extend the
bays. The bays are fully extended when the Slider
Bolts are bottomed out in the slots of the Sliding
Panels.
If necessary, bump or nudge the system into
alignment. Each bulkhead should be aligned along
the centerline of the system.
Recommended attachment points for straps or chains
are at the corners of Front Support on the top and
bottom horizontal channels. When attaching to XL-
XXXL bulkheads, secure as close to the Wing
Assembly attachment points as possible.
NOTE: Be sure not to jerk or pull on the backstop
anchors before the anchoring compound has
cured and the backstop is secured to the
foundation.

STEP 9
Tension Cables and Torque Slider Bolts
Tension the Cables. Torque the cables in 50 ft-lbf [65
N-m] increments alternating between the two.
Reference Torque Chart below (Table 2) for torque
requirements. Use the deep socket provided.
Tighten Slider Bolts to approximately 100 ft-lbf [130
N-m], loosen, and then torque to 20 ft-lbf [27 N-m].
This procedure ensures proper nesting of the panels
and torque accuracy.
NOTE: Care must be taken to not over tighten the
sliders. Follow the procedure outlined above.
