Dust Collector / Vacuum Manifold / Selector

This is a set of workbench-mounted adapters that allows the easy selection of the hose which is connected to my shop vacuum. There are two adapters: one that connects to a 2 1/2" hose and another that connects to a 1 1/2" hose. The intake is selected using a nozzle that connects to end of a 1 1/2" hose which is, in turn, connected to my wall-mounted vacuum: https://amzn.to/2KWFik0
