Works great to connect Ridgid R4512 table saw to Ridgid ShopVac
Too bad Ridgid didn’t think of it themselves, as most folks aren’t going to fork out $$ for a big 4” dust collection system if they are only buying a portable hybrid saw.

Step-down hose adaptor from 4" to 2 1/2" shop vacuum hose
This adaptor allows you to step down from a 4" outlet to the 2 1/2" shop vac size hose. It's a great way to keep a small garage workshop clean when you don't have the larger capacity 2 HP shop vacuum.

Worked for my project
Used this to connect from 4" hose from dust collector to 2" port on craftsman router table using 90 degree elbow. If only it would also get the 10 percent that fall below the table. Guess I need a 10 HP dust collector!
