The 50.8mm Round Knock-In End Cap provides a clean, finished termination for any open end of 50.8mm round stainless steel tubing. The inner stem presses firmly into the tube opening and friction-fits in place — no tools, adhesive, or fixings required. Once seated, the cap sits flush against the tube end, concealing the hollow interior and giving the top rail or infill tube a solid, professional finish.

End caps are one of the most important finishing details in any balustrade installation. An uncapped tube end draws the eye immediately and gives an otherwise well-executed project an unfinished appearance. This cap takes seconds to fit and eliminates that entirely, completing the look at every termination point along the balustrade run.

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