Figured I’d throw a picture up of how I hook my shop vac to the sliding miter saw… Fernco 2” collar is all. Quick and easy. The dust port on this saw isn’t standard anything. It comes with a dust collection bag, but the port is an odd size. I use fernco reducers to adapt all my machines with 4” dc ports to accept a standard shop vac hose. The part that accepts the shop vac hose can be tightened to the point where friction holds the hose nice and snug.

I use the same type of fitting on mine.

So 2” fitting over the port on the saw. I have either 1.25” or 2.5” shop vac hoses, so how do I attach the shop vac to the other side?

I have a 2 1/2 hose on a 16 gallon craftsman shop vac. Even though the fitting is a 2”, the shop vac hose end slides right in to the other end of the fitting. I just snug the hose clamp down enough for a good pressure fit on the shop vac hose, making it a quick disconnect with an air tight seal. It looks confusing because the diameters don’t appear to match up. I’m not sure if it’s a difference between inside and outside diameters, but that connector works with my 2 1/2” shop vac hose.

Hope that helps!
