Ruck 12 inch Fast Clamp | Galvanized Steel, Neoprene Seal, 2-Pack

What the Ruck 12 Inch Fast Clamp Actually Does At 12 in a badly made joint leaks enough to be worth money. The quick-release collar closes it with a galvanized steel band and a neoprene isolating seal, and it does so without tools. The neoprene also keeps the two components from being rigidly coupled, which is where duct-borne noise usually starts. Supplied in packs of two. Fitting a Duct Coupling Clamp So the Fan Stays Serviceable Fit one at each junction so heavy components can be separated without cutting duct. On a 12 in system that is the only sane way to service a fan. Keep expectations straight on noise: the neoprene stops vibration passing through the metal, and does nothing about the air noise in the bore. New seals bed in, so re-check the band tension after a month. Hold a spare back for the day one goes astray mid-install. Key Features Galvanized Steel Band: Corrosion-resistant in the humid air a grow-room exhaust carries. Neoprene Isolating Seal: Seals the joint and breaks the metal path that carries motor hum. Hand-Tightened: No tools, so a fan or filter can be swapped in minutes. 12 in Component Fit: Matches Ruck 12 in fans, silencers and rigid duct sections. Supplied in Packs of Two: One pack does both ends of a single fan. Serviceable Joints: Lets a heavy component come out without cutting into the run.
