Available in steel in 6-, 8-, 10-, 12- and 15-inch diameters with pressure capacity up to 1 in. wg, operational velocity up to 1,600 fpm and a maximum temperature of 240 degrees F.

    Ships factory-assembled with 3-foot cables for easy installation. Cable-operated dampers are easily adjusted via rotary cable actuation using either a nut driver or screwdriver.
