The TNMH line of clamps is used for horizontal lifting and transporting of all non-deflecting plates and structures without marking, scratching and or damaging the material surface. This is accomplished thanks to a jaw and cam that are covered with a high-quality pressure-resistant plastic. Use these clamps for stainless steel, copper, wood panels, aluminum and other similar materials. 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. Available in a range of sizes, with jaw openings from 0.00" - 1.97", and a range of capacities, from 1 - 6 tons.
