DWE7491 dust collection fitting

[Carl Crout]

What kind of adapter do I need to connect my saw to a 4" flexible hose? 2 1/2 to 4"?

[Gary Ragatz]

That's what I use. Mine was part of "Quick Change" kit from Rockler. The 2-1/2 end is flexible, and I keep it attached to the port on the saw with a hose clamp.
