What is a Metal Jacketing Shear?

The metal jacketing shear is designed to cut light gauge sheet metal, plastic, or paper. Metal jacketing shears are used for the protection of thermal insulation in multiple applications. Rolls of material up to 400 lbs are supported by the roller cradle. The material is pulled out under the shear blade and cut by manually lowering the blade.
