Plastic nozzle for applying 1/8" thick ribbons of sealant. Width is 2" but can be modified easily with a utility knife to dispense at up to 4" wide (1/2" increments). Works with sausage, bulk and quart cartridge guns. Ideal for use with our B12S20 sausage gun (see below). Two-piece construction. Designed to apply liquid air barrier sealants and flashings faster than with a trowel.
