The 40 x 40mm Square Knock-In End Cap caps and finishes the open ends of 40 x 40mm square stainless steel tubing. Its inner stem presses into the square tube opening and friction-fits snugly in place, providing a flush, mirror-polished face that closes the tube end cleanly and completely — no tools, fixings, or adhesive required.

The 40 x 40mm profile is the most commonly used square tube in balustrade systems, making this one of the most frequently needed end caps in the range. Used at the ends of top rails, gate uprights, and structural square tube runs, this cap delivers the finishing detail that completes a square-tube balustrade properly.

Manufactured in Grade 316 Marine Grade stainless steel with a mirror polish finish.
