Introducing the 4 in. x 2-1/2 in. Cone Reducer and Key Hose Clamp Set by POWERTEC.

This all-inclusive set includes a sought-after combination of dust collection accessories. One of the reasons this paring is commonly used in woodworking is that most professionals and DIY enthusiasts do not want or need a large dust collection system in their workshop or garage.

Cone Reducer - Designed to provide you with a simple solution to combine your 4-inch ID dust hoses with 2-1/2 ID dust hoses. In particular, it allows you to move from a larger main line to a smaller branch without compromising air velocity or the effectiveness of your dust collection system. Please Note: This reducer is intended for ID ports only. If used with a 4” or 2-1/2” OD port or adapter, a flex cuff, like POWERTEC 70149 or 70148, will be required.

Key Hose Clamps - Allow you to secure your ductwork hoses and connect dust collection hoses to dust hoods, connectors, 4 inch and 2-1/2 inch blast gates, and similar sized dust collection fittings. They feature an easy-to-turn blue key (knob) made from a strong and durable polymer. The key is designed to make the hose much easier to secure and unfasten, by hand and without any tools.
