Fits well with other Rockler products
I got a couple of these unions to join a Y to 2 blast gates.
There is ample thickness to the union and it fit very well to the Y and gates. Included host clamps tightened them up most than enough.

works more perfect than I hoped' Vacuum would not cuple with my Dewalt Planer. Now the vacuum picks up all the dust, shaving, and chips. Now nothing escapes.

Great quality even on something so simple...that’s why I order from Rockler.
Work great… I have used some from the local big box hardware store and the couplers from Rockler work so much better. It’s amazing, you wouldn’t think something so simple would be so difficult to get right but the difference between the hardware store couplers and the Rockler couplers was night and day.

Had been using duct tape to connect my random orbit sander to my shop vac. This coupling should provide a much better connection and be much easier to implement than the duct tape approach.

I recently purchased the Dust Right Universal Small Port Hose Kit from Rockler and, when I received it, discovered that it would not connect to my Craftsman shop vac. After an email conversation with a Rockler employee, I took their recommendation on this union to make the connection.
