RBD – Round Back Draft Damper

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

The RBD is our round back draft damper designed to fit inside the pipe. The welded 2″ deep frame is undersized 1/4″ for easy installation. The .025 aluminum butterfly style blades are attached to the damper using 1/4″ plated rod and bronze bushings. Attached to the blades is a spring closure that seals the blade up tightly against a neoprene gasket.
