Shop notes
Used on: Single-stage and cyclone dust collectors, table saws, jointers and planers.
The 4 in flex hose seats on a port that is 4 in OD at the small end and about 4-1/4 in at the large end. It is a low-vacuum, high-volume line and does not step down cleanly to a shop-vac hose, so a collector and a vac serve different tools.
