SawStop Downdraft Dust Collection Box for Router Lift is designed to efficiently draw dust down from the router bit and channel it to a 4-inch port for effective dust collection. Crafted from durable steel, this dust collection box features interchangeable panels that allow for optimal placement of dust ports and vents. It significantly reduces router noise while providing a convenient connection by plugging the 2.25-inch dust hose from the router fence directly into the dust box branch inlet. The 4-inch port effectively collects dust both above and below the table from a single outlet. Compatible with all SawStop Router Tables, this dust collection box ensures a cleaner and quieter working environment. Model Number: RT-DCB
