Create a healthier, more productive growing environment

Greenhouse exhausting is critical for reducing plant and worker stress. Happy Hydro Worm Gear Duct Clamps let you establish firm, enduring flex duct connections quickly and efficiently. Available in your choice of 6", 8" or 10" sizes, our 4-piece kit boasts enough ducting clamps to connect 1 full ventilation loop of a carbon filter, exhaust fan and hood.

Designed for durability and easy use

Happy Hydro Duct Clamps are made of non-corrosive stainless steel so they are impervious to climate extremes, humidity and precipitation. Their 1-piece hex head housings allow for spot weld-free installation with just a flat-tip screwdriver or nut driver, and the worm gear design ensures secure, vibration-proof connections to fans, hoods, hose lines and more. Take the frustration out of greenhouse exhausting set-ups, HVAC ventilation and other heating / cooling applications.

A multitude of uses

Hydro Happy Worm Gear Duct Clamps are perfect for attaching ducting to fans, connectors, Y's and reducers, as well as any item that has a duct flange. You can rely on them for bundling or sealing air, gas or fluid hose lines. Their simple screw tightening method creates a strong clamp force that withstands shaking and high-speed vibrations associated with fans and other machinery. If Happy Hydro Clamps do not perform as promised, return them within 30 days for a full refund of your purchase price.
