End Cap – Knock-in – Square – 50 x 50mm

The 50 x 50mm Square Knock-In End Cap provides a clean, finished termination for open ends of 50 x 50mm square stainless steel tubing. The inner stem presses firmly into the square tube opening and friction-fits securely in place, sitting flush against the tube end to conceal the hollow interior with no tools, adhesive, or fixings required.

The square profile of this cap means all four faces sit flush and level with the tube walls, maintaining the crisp, flat-faced geometry of the square tube right to the very end. On a 50 x 50mm post or top rail, this cap is a visible detail — and a well-seated, flush square cap signals a quality, considered installation.

Manufactured in Grade 316 Marine Grade stainless steel with a mirror polish finish, suitable for all outdoor and coastal environments.
