Threads directly to the front cap (426-G01) of Albion Deluxe & Special Deluxe drive guns (DL-45, DL-59, etc.).
Or, use a 966-2 adapter for use with B-Line sausage guns.
1/2" ID. Includes coupling to attach any other standard Albion metal nozzle or another extension.
Remember that as the nozzle gets longer it becomes harder push material through. Consider using with a high-thrust Plus Drive, Ultra Drive or B26 Drive.
