Lambro 142R Rigid Rectangular Duct Connector
The Lambro 142R is engineered as a rigid rectangular connector with vibration-attenuating features that make it particularly well-suited to stable ventilation systems where noise isolation and mechanical decoupling are required. Unlike simple metal couplers, the 142R focuses on reducing transfer of fan vibration into ductwork, offering a technical advantage for occupational comfort and system stability—even if its unit cost can be higher than a bare-sheet-metal coupler. This product is released and available now and is often specified where both airtightness and vibration control are critical.
