Our hole plugs are available in a range of sizes (shown in mm). Each plug is precisely CNC-machined from high-quality 6060 T5 aluminium, known for its excellent strength-to-weight ratio, corrosion resistance and smooth surface finish. Designed for a flush, professional look, these aluminium hole plugs provide a permanent mechanical fit without the need for adhesives or welding.

With a total thickness of 3mm and a subtle chamfer on the edge, they install cleanly and sit securely in place - ideal for both indoor and outdoor applications where durability, performance and visual appeal matter.
