UFO & Stopper Sleeves The Universal Fastening Object The UFO is the only universal, single-piece fastener that quickly and securely bonds solar modules to XR Rails. It comes lubricated and assembled, with a sleek, low-profile design. Simply snapping on a Stopper Sleeve transforms the UFO into an end clamp.
The UFO is a part of the IronRidge Integrated Grounding System, which is listed to UL 2703 and eliminates the need for separate grounding hardware. Comes in black and mill finish.
Secure Elecrtrical Bonding UFO hardware forms secure electrical bonds with both the module and the rail, resulting in many parallel grounding paths throughout the system. This leads to safer and more reliable installations.
Transform Mid to an End Clamp The Stopper Sleeve snaps onto the UFO, converting it into a bonded end clamp. Stopper Sleeves available in sizes: 30mm, 32mm, 33mm, 35mm, 38mm, 40mm, 42mm, and 46mm.
