The Dust Muzzle has a 1.25” female exhaust port and accepts a 1.25” tapered male hose fitting. If you do not have a vacuum hose with this fitting, you will need our step-down hose. Our step-down hose is 4 1/2 feet of lightweight blow molded hose that has a 1.25” male fitting on one end and a 2.25” female fitting on the other end. It attaches directly to the male end of all American industrial shop vacuum hoses. It extends the hose that comes with your vacuum by 4 1/2 feet.
The above photo shows a shortened version of our hose. The standard vacuum hose is on the left.
