Nvent ADK421RD Strut End Cap Eristrut Type-a Type-c Red

Product Description

The NVENT ADK421RD is a polyethylene strut channel end cap designed to close off open ends of ERISTRUT strut channel installations. Measuring 1-5/8 inches in length by 1-5/8 inches in width, this red end cap snaps into place to cover exposed channel ends, protecting workers from sharp metal edges and giving the finished installation a clean, professional appearance. Made from polyethylene, the cap resists moisture and common jobsite chemicals. Electricians and mechanical contractors install these caps as a final step in strut channel support system assembly in both commercial and industrial settings.

The ADK421RD fits ERISTRUT Type-A, Type-B, Type-C, and Type-D strut channel in both slotted and solid configurations. When the two halves are separated, each piece functions as an individual end cap for ERISTRUT Type-C channel, covering the smaller 13/16 inch by 1-5/8 inch profile. This dual-use design reduces the number of separate part numbers needed on a job, making it a practical choice for shops and service vans stocking strut hardware.

Installation Notes

Installation is typically performed by licensed electricians or mechanical contractors as a finish step after strut channel supports are fully assembled and fastened. No special tools are required - the cap presses or snaps onto the open channel end by hand. De-energize any electrical systems routed along the strut before performing finish work in the area. Verify that the channel type and profile match the cap dimensions before installation.
