K2 Systems 4000090 30-40mm CR Silver End Clamp

K2 Systems CR Silver End Clamp, 30–40mm (4000090)

The K2 Systems CR EC Silver End Clamp (Part No. 4000090) is a precision-engineered solar module fastener built to anchor the outer boundary panels of a PV array directly to K2 mounting rails. Designed to accommodate standard module frame heights between 30mm and 40mm, this mill-finish clamp delivers high structural holding power across K2 racking systems, including CrossRail, MiniRail, and compatible profile channels.

Manufactured from high-grade aluminum and corrosion-resistant stainless steel hardware, the assembly is built to withstand high wind uplift, snow loads, and severe outdoor exposure without rusting or degrading over time. Each set comes equipped with an MK3 slot nut, clamp spring, lock washer, and M8 cap head screw, ensuring rapid, top-down rail attachment for both commercial installation crews and DIY solar builders. For installations featuring dark-framed or all-black solar modules, K2 offers the same structural performance in their Dark End Clamp Set (4000233).
