The CHE-1/2 aluminum nozzle holder is for use with 3/4" threaded (standard) nozzles and blast hoses with a 1/2" inside diameter and 1-3/16" outside diameter. This nozzle holder attaches to the end of the blast hose (with included screws) and holds the blasting nozzle.
Note: screws are included with holders but washers come with nozzles.
Got what was ordered. Worked as needed.
