Ruskin’s TED40 Economy Insulated Thinline Control Damper provides low leakage and thermal performance in a thin line, 4-inch-deep frame. The blade profile stays in the full open position, making it ideal for mounting against louvers or openings, company officials say. The damper has an extruded aluminum frame and blades, polyurethane foam-filled cavities for added thermal protection, molded synthetic axle bearings and extruded Ruskiprene blade seals locked into the blades, among other features.
