EFO End Fastening Object
Universal End Clamps for XR Rails
The IronRidge EFO is here. We redesigned the end-clamp system for XR Rails, which originally used Stopper Sleeves to turn UFO mid clamps into end clamps. Those slowdowns are no more.
End Fastening Objects-EFO-provide enhanced engagement on modules and support frame heights of 30 to 40mm. This universal end clamp is a single-piece component that speeds up installation times, especially when modules vary by project.
Module Tolerances for Frame Thickness Can Vary
Having a specified height of 30mm does not always mean a module will arrive on a roof that precise. EFO is universal to make installs easier. And an integrated bonding pin under the clamp head ensures it remains flush to the module when being tightened down.
A key feature that mimics that of the UFO is the long T-bolt that gives the clamp a sleek, simple appearance. This lets it incorporate seamlessly into XR Rails, allowing for installation across many applications - Flush Mount, Tilt Mount, and Ground Mount.
No More Show Stoppers
On-site assembly of Stopper Sleeves is no longer required on XR Rail projects.
IronRidge is always focused on ways to streamline installations and EFO is yet another example of that commitment.
The Installation Process
Fasten end solar modules to XR Rails using the EFO on each rail end.
Ensure clamps are hooked over the top of each module and held squarely in place while being tightened.
Torque EFO to 80 in-lbs.
