A. CONNECT SPLICES
Use Bonded Splices, when needed, to join multiple

secure with two self-drilling screws, spacing them about
1” apart and torquing to 20 in-lbs. Slide second rail over
Bonded Splice and secure with two self-drilling screws.
í Rows exceeding 100 feet of rail must use Expansion Joints.
í For XR10 and XR100 rails, insert screws along the provided lines.
í Refer to Structural Certication letters for rail splice location
requirements.
í Screws can be inserted on front or back of rails.
í If using Bonding Bolt Splices, refer to addendum (v1.0).
B. ATTACH SOUTH RAILS
Slide 1" long bonding bolt into side-facing rail slot. Mount
rail to pivot bracket of South Legs and loosely tighten nuts.
C. ATTACH NORTH RAILS
Slide 2.25" bonding bolt into side-facing rail slot. Mount rail
to top of North Legs. Tighten all 3/8” hardware to 250 in-
lbs once rails are square.
