United Scientific Chain Clamp
Hold objects that are too large for standard clamps, such as glass distillation columns and odd-shaped glassware, with this handy chain clamp.Â
The chain links bend to conform to the shape of the object being held. The tension spring locks the chain links in place to firmly hold objects.
Both chain and support band are made of strong chrome-plated brass. The chain is  21 in. long and can be adjusted to support apparatus from 2 in. to 6-1/2 in. in diameter.
The support rod is constructed of stainless steel and measures 0.46 in. dia. x 8-1/2 in. long.
