Shop notes

Found on: Most bench and cabinet router-table fences with a rear dust port.

A router-table fence port is usually a 2-1/2 in inner-diameter socket with a 2-11/16 in outer diameter. A 2-1/2 in shop-vac hose cuff pushes straight into it, which makes the router table one of the few tools that needs no reducer.
