Shop notes

The port measures about 32 mm and the hose about 32 mm, the same, so the port seats inside the hose as a friction fit. No reducer is needed for this pairing, so the DeWalt DWP611 compact router port and the 1-1/4 in shop-vac hose connect directly.

It is a push fit, not a lock. Seat it fully and check it has not crept loose after a few minutes of vibration before you trust it on fine dust.
