At Salco, we offer a line of pneumatic plier staplers that is ideal for a variety of industrial applications. Our selection includes pneumatic plier staplers for light, medium, and heavy-duty packaging, corrugated container, and shipping tube end-cap applications. Unlike traditional staples, industrial pliers work via a squeezing motion. This provides a more comfortable experience, especially when used for long periods. If you need to staple through many layers, opt for one of our heavy-duty models. These heavy-duty pliers can staple through six layers of cardboard. If your main application is assembling box tops, corrugated trays, or lids, opt for a lightweight model.
