IPH10 clamps are made for the horizontal lifting and transfer of non-sagging material. These clamps should always be used in pairs (a minimum of two clamps per lift), and the Working Load Limits shown below are based on one pair of clamps, not per piece. And with the exception of the two smallest sizes, these clamps feature two great updates: 1) Magnets ensure the clamps remain in the proper position on the plate and 2) A handle and torsion spring that combine to make the placing of the clamp onto the plate quick, easy and safe. Available in capacities from 0.5T - 12T (metric rated) with a wide range of jaw openings. Manufactured in an ISO 9001 facility, each clamp is RFID equipped. The serial number and proof-load test date are permanently stamped into the clamp body.
