COX Caulk Gun: Bulk Container, For Spray and Bead Application Application Type, For 600 mL Container

The barrel of these air-powered guns holds bulk caulk. The guns press their plunger against the caulk packed in the barrel end and squeeze caulk from the top of the barrel and through a nozzle attachment on the gun. They leave no packaging to dispose of but require cleaning after every use to remove caulk residue.
