How to order the correct size End Cap

Nelsons CNC End Caps are made from aluminium. It is important to know exactly what size material you are capping as each end cap has been designed to fit specific aluminium extrusions.

Check the wall thickness of your material and the outside dimensions and whether the extrusion has a radius edge or square edge before placing your order. (R = Radius Edge).

End Cap sizing explained

Let's use one of our Square End Caps with Radius Edge as an example 50x50x3 R6.
A = Outside dimension (50mm)
B = Outside dimension (50mm)
C = Wall thickness (3mm)
R = Radius Edge (6mm)

Custom Sized End Caps

Please check our extensive range of sizes in our online shop before contacting us for a custom sized end cap. We create custom end caps from die drawings or diagrams of your extrusion you are wishing to cap. Please email your dwg/dfx file with quantity required to orders@nelsonscnc.com.au.

No, our end caps are made to fit into the end of aluminium extrusions and can not be fitted into wood.
