50 x 50 Black plastic plugs

These 50 x 50 Black Plastic Plugs are robust square inserts crafted for use with 50mm x 50mm steel, aluminium, or PVC tubing. Made from high-quality plastic, these plugs ensure a secure fit, preventing dirt, moisture, and debris from entering the tubing. Ideal for indoor and outdoor applications, they help reduce wear on surfaces by creating a smooth, protective end on table legs, fence posts, railings, and various other structures. Their simple push-fit design allows for quick installation, while their black finish offers a sleek, professional appearance that blends well in modern and industrial design settings.
