Dust Right® Combo Port

Item #
98% of 100

This versatile port expands options with fittings for either the Dust Right® Handle (sold separately) or standard 4" hose (sold separately). It mounts to router table cabinets, downdraft table cabinets and other boxed-in dust reservoirs for either quick-release or permanent suction - your choice! The Rockler Dust Right® Handle fits snug over the cylindrical base of the port, tool-free. The slightly smaller outer fitting accepts 4" hose.

Just like all the Dust Right products, this one is well made and it works perfectly in a system. Well made at a good price, no worries!

Sanding Drawer
I made a drawer (box with holes in the top) that slides from under the bench top for sanding. Mounted this port on the bottom and it works very well.

Good value for the money.
Nice, sturdy design. Accurately sized to connect to other Dust Right components securely but still allowing fairly easy disconnecting. I l

Works perfectly for my dust collection system
Had one of these on my router table setup and wanted to use the handles (from Rockler) on my Laguna LT16 band saw and on my soon-to-be-built double intake miter saw dust enclosure. So I bought three and they work perfectly to quickly hook up double 4 inch flexible hoses to (soon) all my dust creating tools!!
Good product. Well designed. Dust sucks!!

These work perfectly for attaching my old vacuum system in my shop. They fit tight and give me the opportunity to move around my shop for small tool dust collection. Love them!

Would be nice if a "Cut Out" template came with it. Very durable and convenient for vac hook up
Would be nice if a paper template came to transfer "cut out" opening. Very durable and convenient

Perfect fit
It fit well on my grizzly 14 inch band saw. It will stay on just by pushing it on and stay on without the need of any clamps

Easily installed
Built my own collection system for my miter saw and this was the last component needed to make a connection to my dust collection system. Sturdy and well constructed. Does the job.

because the quick change ports only come in pairs, and while they are great, I only need one more connection right now, and this should fit the quick change perfectly

BEST ANSWER: Yes it does,
What fitting do I need to attach a four inch hose to the back of this fitting?
Robert B on Mar 29, 2017
BEST ANSWER: I didn't use a fitting. I have a four inch flex hose double loop quick release clamp directly to the fitting. Works very well slips on and off easily, hose is shared between two pieces of equipment. I think dust right makes a quick connector but this works just as well
I have 4" quick change handle and need a fitting that will connect to a 3" tool port. Where can I find this fitting?
Tom L on Jun 10, 2018
The outlet starts with a kind of rectangular shape, what is more efficient, just cut 4 inch round hole and leave it or should cut same shape(kind of rectangular shape) as the outlet starts ?
