Attach branch lines to more than one machine. Reduce your branch offs down to 4-Inchs. Improves efficiency of your dust system. Improves lateral air flow. For best connection use hose clamp (not included).
DO NOT buy if you want the 5 inch ID as advertised. Its inside diameter is 4 15/16 inches (outside diameter is 5 3/16 inches). This will NOT fit the 5" Super Dust Vice connector I bought it for. Unfortunately there are no zero stars.
