The 50 x 25mm Rectangular Knock-In End Cap provides a clean, finished termination for open ends of 50 x 25mm rectangular stainless steel tubing. The inner stem presses into the rectangular tube opening and friction-fits firmly in place, capping the hollow interior with a flush, mirror-polished face — no tools, adhesive, or fixings required.
The rectangular profile of this cap follows the wide, flat form of the tube precisely, sitting flush across both the wide and narrow faces simultaneously. On a 50 x 25mm top rail, the end cap is a prominent finishing detail — the flat, wide face of the rectangular tube draws attention to its ends, and a clean, flush cap ensures that detail is as polished as the rest of the installation.
Manufactured in Grade 316 Marine Grade stainless steel with a mirror polish finish, suitable for all outdoor and coastal environments.
