Fence Post Caps

Precision-made fence post caps for a perfect aluminium finish

Nelsons CNC manufactures premium fence post caps that deliver a permanent, precision fit for aluminium fencing, balustrades, facades and handrails. They offer a durable, friction-fit solution that eliminates the hassle of welding or unreliable plastic alternatives. Just five taps with a rubber mallet, and the cap is permanently in place.

Unlike generic plastic fencing caps that crack, fade or loosen over time, our metal end caps are built from 6060 T5 aluminium for a hardwearing finish that stays put. The 6060 T5’s main selling point is its high-quality aluminium construction, offering durability and the ability to withstand the elements for various applications like fencing and balustrades.

Need a finish that blends in? Our metal fence caps can be powder-coated to match your project exactly, avoiding colour mismatches across fencing and structures.

Custom sizes and free sample caps available

We stock fence caps to suit all standard square, round and rectangular hollow sections. If you need a non-standard size, we offer custom-sized caps made to your exact extrusion. Not sure which one fits best? Ask us about free sample caps to test on-site before you order. Our team can also assist with sizing and product selection.
