What the Ruck 8 Inch Fast Clamp Actually Does
Galvanized sheet steel band, neoprene isolating seal, 8 in bore. It measures 8 x 2.4 in and weighs 1 lb. The clamp closes by hand and holds a fan, a silencer or a length of rigid duct against its neighbour. Neoprene between the faces stops vibration transferring along the run. Sold in packs of two.
Fitting a Duct Coupling Clamp So the Fan Stays Serviceable
Put one at each end of the fan and it becomes removable without touching the rest of the run. That matters more than it sounds on an 8 in system, where the fan is heavy enough to be awkward. The seal handles structure-borne noise only. Air noise still needs a silencer in the duct. Give the band a re-check once the neoprene has bedded in, usually within the first month. A spare in the toolbox is worth having; the band is the part people mislay.
