RocklerDust Collection Fittings – Polymer Dust Right Quick Change Multi-Port Tool Set w/Quick Change Handle, 2.5'' to 4'' Tool Ports, 4'' Keyed Bridge Hose Clamps – Shop Dust Collection Fittings

Very easy to put together.Good quality material. Will be so handy in the workshop .

I like it. It works well.

This makes changing from machine to machine much faster. No more tape on the joints. If you’re like me and dust collection is a problem and you don’t have space for dedicated shop vacs at every machine and you don’t want to go through the headache of running pipes everywhere this will help.

Fit was perfect and easy to set up.

If you have more than one tool in your shop that uses a dust collection system, these connectors are a must! It makes changing your dust collector hose from one machine to the other a snap! Just make sure the clamps are good and tight as I've pulled the connectors off of the machine trying to take the hose loose from one to move it to the other. Once the clamps are good and tight, you'll have no trouble.
