Designed specifically for GREAT STUFF PRO Drywall Gasket Gun Foam (W-GSPF) the blue-handled dispensing gun has a 7-3/4in barrel that allows for precise application of the foam. It is reusable and can be easily cleaned using a garden hose and the included cleanout adapter.

Note: The traditional polyurethane GREAT STUFF PRO Dispensing Gun is not adequate for dispensing this latex-based technology. These guns are not interchangeable.
