Unirac SOLARMOUNT Bonding Mid Clamp

Unirac SOLARMOUNT Bonding Mid Clamp

The Unirac SOLARMOUNT Bonding Mid Clamp is a structural racking fastener engineered to secure adjacent photovoltaic (PV) solar modules to Unirac SOLARMOUNT rails while establishing integrated UL 2703 module-to-rail electrical bonding. Installed in the narrow gap between neighboring solar panels, the clamp's dual-lip design grips adjacent module frames evenly to lock them securely against high wind uplift and heavy snow loads.

Featuring integrated bonding pins, the clamp pierces the anodized coating of the solar module frame upon tightening, creating an immediate electrical path to the rail without requiring extra grounding lugs or copper jumper wires. Available across multiple color finishes, frame height profiles, and US-manufactured options, it delivers a clean, professional look for any rooftop solar layout.
