Tech Team #703 4” X ½” Wide, KeyStyle, Stainless Steel Hose Clamps for Dust Collection and Clothes Dryer Vent Hoses Pack of 6

Tech Team’s #703 4” key tensionerstyle stainless steel ½” band gear clamps are perfect for 4inch dust collection hoses and 4” inch dryer vent hoses. The halfinch wide #304 stainlesssteel band fits hoses from 2” diameter up to 4 ½” for dust collection hoses and clothes dryer vent hoses. The keystyle screw mechanism allows for one hand tightening of clamps in confined spaces for a leakproof seal. The oversized 100% steel tightening key is superior to color plastic keys that can break under stress and the heat typical of clothes dryer vent applications. Pack of 6.

Clamps should be doubled up on both ends of the hose. One with the key/screw on the left, and one on the right. This ensures uniform tension and a tight connection in applications where heat and vibration are present. These are the best dust collector and clothes dryer hose clamps available anyplace.
