Our products are engineered to make your project easier. Our Manual Remote Control (cable operated) Dampers provide balancing for inaccessible ducts and take-offs. The prime application is on multiple inlet linear/slot plenums with the adjustment tip mounted immediately behind the air outlet. Alternate situations such as branch ducts, may have the cable run externally to a ceiling mounted termination with a cover plate. We are always ready to assist you in designing the right damper system for your needs. Specialized and custom designed systems are also available. Just call or find a distributor near you.
