The 12.7mm Round Knock-In End Cap is the finishing cap for the slimmest round tube in the Balustrader range. Its inner stem presses into the 12.7mm tube opening and holds firmly by friction, capping the hollow tube end with a flush, mirror-polished face that completes each infill run cleanly and precisely.
At 12.7mm, the tube and cap are both fine, minimal details — but in a high-density infill configuration where multiple thin tubes terminate at the same point, a consistently capped row of 12.7mm tubes reads as sharp and intentional rather than unfinished. This small cap is the detail that closes the gap between a good installation and a great one.
Manufactured in Grade 316 Marine Grade stainless steel with a mirror polish finish.
