Albion Engineering Company Nozzle. Designed specifically for applying sealants and moisture and air barrier coatings, it does it much faster than if you were working with a trowel. A very important feature of this nozzle is its versatility. It produces a strip of sealant that is 1/8 inch thick and 2 inches wide. You can easily change the width of the strip up to 4 inches by simply trimming the nozzle with a regular construction knife, and do this in 1/2 inch increments. Suitable for different types of sealant guns and for working with cartridge tubes and even bulk packs. Made of high quality plastic, sturdy yet lightweight.
