Made of hardened high carbon spring steel, Carpin’s metal tube closures provide an attractive and reliable solution for enclosing the ends of metal tubes.
Carpin offers metal tube enclosures that feature ‘turned in’ spring legs that press against the ID of the tube to securely hold the end cap in place.
An alternative version of the metal tube enclosure uses ‘turned back’ prongs to offer a sharper bite into the ID of the tube, thus providing enhanced holding power while attractively concealing the cut edge of the tube.
Metal tube enclosures are commonly used to cap off the ends of tubular furniture and shelving products.
