COX Caulk Gun: Sausage Pack, For Low to High Viscosity Materials Application Type, Enclosed Frame

Sausage packs (chubs) fit into the barrel of these air-powered guns. The guns press their plunger against end of the pack and squeeze caulk from the top of the pack and through a nozzle attachment on the gun. They compress the pack to a small plug, leaving less packaging waste than cartridge guns. They sometimes leave behind caulk residue, which requires the barrel to be cleaned out before loading a new sausage pack.
