Clamps D-13

Ductile ClampsWe back our clamps with a limited lifetime warranty on the clamp bodies. We will replace any ductile iron clamp body that cracks or breaks under normal use for as long as the original purchaser owns them, and Grade 2 bolts are used. (See Warranty Information for details.)
