The Roberts Adhesive Applicator Nozzle, also known as snozzle, spreads 11 rows of adhesive at a time. This creates a flat, well-bonded installation for professional results and minimal repairs. The nozzle fits most standard 11 oz. and 30 oz. cartridge application guns. The nozzle can be reused if cleaned after each use. This helps you save money and is good for the environment.
