BDD – Back Draft Damper

Sheet Metal Connectors is proud to distribute and sell Standard Metal Products dampers and louvers.

The BDD dampers offer back draft protection in light duty applications. The damper frame is a 16ga welded galvanized construction that is undersized 1/4″ to fit inside the duct. The .025 aluminum blades are attached to the frame with 1/4″ round plated rod and bronze bushings. The stamped aluminum brackets and linkage keep the blades operating together and the felt blade stops provide for quiet operation.
