2-inch Standoff Collars with Damper (Conical E-Z Tap)
Sheet Metal Connectors’ standoff collars are fabricated from galvanized steel. These collars have a crimp and stop bead on one end. The volume damper is made out of 20 ga. galvanized steel with stiffening beads and a continuous 3/8” aluminum square shaft for strength and rigidity. Nylon end bearings are added to each end to reduce air leakage. All standoff collars have a 3/8” dial regulator elevated 2” for insulation.
