Round End Caps

Round End Caps

Nelsons CNC round end caps are made for finishing round aluminum tube and extrusion ends with a clean press-fit cap. They are CNC-machined for accuracy and designed to install with a rubber mallet, with no welding or adhesive required.

Also see Square End Caps, Rectangle End Caps, Aluminum End Caps, and Custom Size End Caps.

For sizing and material choice, see how to measure round tube for end caps and why aluminum end caps outperform plastic caps.
