The #720 Klinch-It Hand tool is quick and easy to use. Klinch-It lowers your production cost and increases your production by speeding up one of the most time-consuming operations. It eliminates the slow, old way of sewing springs to the web base. Instead, the springs are permanently fastened with sturdy steel clips. Simply fill the magazine with two strips of fasteners, hold the tool upright, place the nozzle over the spring, press down so that the prongs of the fastener pierce the webbing, then squeeze the lever to complete the fastening. The overall length is 27" long, width is 2", and the weight is 3-3/4 lbs.
