Suspended Clamps

Suspended pipe clamps and tube hangers in 1/2" through 2", for supporting pipe from joists, decking and overhead structure.

A suspended clamp carries the pipe below the structure rather than strapping it to a face, which is what a horizontal run through open joists or above a dropped ceiling needs. Spacing is set by code and by pipe material — plastic sags at temperature and needs support far more often than copper or steel, and the interval tightens again on hot lines.

Isolation matters at every contact point. A bare steel clamp on copper starts galvanic corrosion where the two touch, and a rigid metal-to-metal clamp transmits water hammer and expansion noise straight into the framing, which is what you hear as ticking in a finished ceiling. Cushioned and plastic-lined versions solve both.

Leave room for movement. A clamp tightened hard onto a hot-water line stops the pipe expanding lengthwise and the stress goes into the joints instead.
