The C821 is a classic half-barrel skeleton caulking gun that combines durability with everyday practicality. The sturdy blue-painted steel barrel partially surrounds the cartridge to protect it on site, while the smooth round thrust rod slides cleanly through the sealant gun mechanism for reliable dispensing. With a full contoured grip, instant-flow release and a hanging hook, it is a dependable everyday tool for painters, installers and maintenance teams.
