All of Ductmate’s dampered fittings feature our exclusive, die-cast zinc aluminum low-leakage damper hardware. Our patented design seals the collar penetration on all dampered fittings, reducing leakage.
Dampered fittings may also be ordered with 1½” or 2” stand-off hardware. Complete stand-off kits are also available for retrofit jobs. All fittings are available with blue or yellow union label.
