The Duro Dyne BKO-3 Opax Blade Kit, MPN 002003, is made for opposed action dampers to improve air control. This kit minimizes turbulence and supports more linear airflow management. Its Neva-Bind technology features four-way self-adjustability. This allows for compensating construction variances while ensuring consistent operation.
This kit keeps linkage points aligned during usage, preventing any rattling or fluttering of the damper blades.
