How to Install
How to install End Caps
Easy install, knock-in with a rubber mallet for a permanent fit*, no adhesive or weld required. A beveled edge on the underside of the cap makes for easy installation. Cap will fit firmly if installed correctly.
Correct permeant fitment of Nelsons CNC aluminium end caps is dependant on;
– Correctly prepared profile edges of extrusion.
– Correct end cap and profile dimensional synergy (refer to spec)
– End cap should be a tight fit with no movement after installation.
– End caps are intended for static (non-vibrational environment).
Correct fitment can be affected by ambient climatic change, care should be taken to access the location and safety of each item where such environmental conditions can occur.

Have a question?
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. Measure the external dimension of your extrusion, wall thickness and note if your extrusion has a square or radius edge. To ensure your aluminium caps are a perfect fit we recommend measuring your extrusion with a vernier.
Our end caps are named according to size: Example 50x50x3 R6
A = 50mm (Outside dimension)
B = 50mm (Outside dimension)
C = 3mm (Wall Thickness)
R = 6mm (Radius Edge)
