What the Ruck 4 Inch Fast Clamp Actually Does
This is the quick-release collar that joins two 4 in ventilation components without a screwdriver. It is galvanized sheet steel with a neoprene isolating seal running inside the band. That seal is doing two jobs at once. It closes the joint against leakage, and it breaks the metal-to-metal path that carries motor hum down the duct. They ship in packs of two.
Fitting a Duct Coupling Clamp So the Fan Stays Serviceable
Use one at each end of the fan so the unit can be lifted out without cutting anything. That is the practical argument for clamps over screwed flanges: a filter change or a motor swap becomes a two-minute job. Do not treat the neoprene as a substitute for a proper silencer. It damps structure-borne vibration, not the air noise coming down the bore. Check the band after the first few weeks, since a new seal beds in and can go slightly slack. Keep one spare in the box, because clamps go missing before ducting does.
