Lau’s standard galvanized steel control dampers feature sturdy, steel construction with interlocking frame design. The dampers lock together without bolts, screws or rivets that could shake loose. Frame corners are internally braced to reduce racking.
Axles positively lock to blades without screws or welds. Non-stick, non-corrosive bearings assure long life and ease of operation. Axles and bearings combine with a shake proof linkage for low maintenance operation.
