Durable
Exhausting your grow room is very important for your plants health. LUMAGRO's Clamps are made of non- corrosive stainless steel so they are impervious to climate extremes, humidity and precipitation. The 1-piece housing allows for weld-free installation with just a flat-head screwdriver, and the worm gear design ensures secure, vibration-proof connections to fans, reflectors, duct lines and more. 
Versatile Size
 Clamps are perfect for attaching ducting to reflectors, inline fans, Y-connectors, reducers, dampers, and more. The easy to use screw tightening method clamps onto flanges with strong force that can withstand high vibrations caused by other fans and/or equipment.
