COMBINATION ADAPTORS / REDUCERS
The inside diameter of the 2 1/2" side of each of these fittings duplicates the 2 1/2" opening on your home shop vacuum. Insert the home shop vacuum hose to the vac and the other end to one of these fittings to power the dust collection system. The outside diameter matches the standard duct collection hose to function as regular reducers.
