Rule your rail.
The BOSS™ (Bonded Structural Splice) provides a strong, bonded connection for XR Rails.
No assembly, tools, or hardware required. The built-in bonding spring has teeth that bite into rail, creating a connection that meets all UL standards.
The BOSS™ eliminates restrictions around splice locations. Place it anywhere along the span (except the outside cantilever).
Available now, so you can continue to conquer your solar projects!
Place into XR Rails anywhere, except the outside cantilever.
Single piece, with no assembly, tools, or hardware required.
Splices are available in all rail sizes—XR10, XR100, and XR1000.
Centered stop tab provides tactile feedback for proper installations.
No more bonding straps! Just leave a 1″ gap for expansion joints.
