Dust Extraction Fitting, Funnel Reducer, 4" x 2-1/4"
This fitting gives you the advantage of a pliable material that flexes more than the traditional ABS that makes up most dust extractions. This is especially important in installations where the reducer lies on the floor and is prone to an occasional stumble or bump. The smooth transition from 4" to 2-1/2" allows the user to connect their 4" ported equipment to a shop vacuum with only a minor loss in flow.
