IronRidge UFO-END-01-B1 End Fastening Object
The IronRidge EFO (End Fastening Object) is a single-piece, universal end clamp designed for securing the end of solar modules to IronRidge XR Rails. It supports solar panel frame heights from 30mm to 40mm and eliminates the need for additional Stopper Sleeves that were previously required for turning mid clamps into end clamps.
This redesigned system enhances module engagement and accelerates installation by simplifying the clamping process, especially in applications where module frame heights vary slightly. It also features an integrated bonding pin that ensures secure grounding while maintaining a low profile for clean aesthetics.
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.

As a DIYer, it's all plug and play, so it's incredibly straightforward... you have certified engineers doing your designs, therefore they're gonna be safe electrically and structurally. That to me is a big peace of mind when I did this.

You guys are my guys when it comes to solar. When I got stuck, making a phone call or appointment was one of the huge keys to how well this worked. The confidence and encouragement... it validated that I could do it.

Once I got the plan set, it was easy to install... it was amazing how quick it went once everything was all set up. I knew what to expect, I knew what the inspector would be looking for... you guys were there to back me up, so it was the smartest option for me.
