WoodstockD4256 4" 45 degree Elbow, NULL

It's a dust collector fitting....how much can you like a piece of plastic?

Came in 2 days, well made elbow. Used for my dust collection system.

Using two of these is way less restrictive than some of the 90s that are sold where the pipe almost flattens on one inside edge. These worked flawlessly for my application.

Using it for dust collection from a CNC router, works great. It lasts about 4 months with the machine running around 16 hours a week.
