This square bypass damper (CRHA) provides precise HVAC air control with simultaneous moving blades and an almost hermetic closure. Constructed from G90 galvanized steel with 16-gauge galvanized blades, stainless steel lateral sealing, and neoprene blade seals, it is built for durability and reduced air leakage. Available in custom sizes up to 48" x 24", this damper can be supplied with an assembled electric actuator when that option is selected.
