4" reducer 2-1/4
This is a no brainer. Must have this to connect a dust collector with 4" line to the bandsaw, or anyother 2-1/4" connecting device. Consider it standard shop requirement. It fit perfect to several of my machines.

Easy to use adapter
Was easily able to attach my Bosch table saw to my shop fox 4" dust collector which minimizes aerosolized sawdust to which I'm allergic. All in all, a sine qua non.
