Rockler Flexiport Hose to PorterCable Biscuit Joiner Adapter

The Rockler flexi hose is great, but changing the adapters is tedious. The adapter is tapered on the biscuit joiner end and ribbed on the Rockler end. The hose stays secure. The model is sized so that a wrap or two of electrical tape on the porter cable port is enough to secure it tightly.

The wider adapter clogs less. Using a dust collector with a biscuit joiner results in better cuts and fewer clogs.
