Keep 1/2 in. - 5/8 in. supply tubing firmly in place on a variety of surfaces using the Support Clamp. Clamp holds down tubing along walls, posts, and fences; or aligned along beams, decks, and patios. Sturdy clamp comes with a nail to attach onto nail-safe surfaces; the rounded bracket keeps supply tubing in place without pinching. Prevents supply tubing from kinking or bending. Remove and reuse easily when you need to move or change your drip system. The support clamp is made of polyethylene treated with UV inhibitors, and includes a metal nail.
