RBD – Round Back Draft Damper

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.
