Shop notes
Found on: Table saws, jointers, planers, bandsaws and drum sanders with a 4 in collection port.
The 4 in machine port measures about 3.9 in outer and 3.6 in inner, so a 4 in flex hose seats over the 3.9 in OD. It is the standard stationary-tool port and pairs with a dust collector, not a shop vac.
