The dimensions were acceptable and it worked. What more can you ask of a static piece of metal.

One part of the puzzle
We're building a dust collection system for a 700 sq.ft. wood shop at Milwaukee Makerspace; a community workshop and non-profit group for makers, crafters, etc. I've bought seven or eight of these so far. The main duct to the dust collector is 6" round and the takeoffs are 6" wye fittings with one of these reducers on the leg. We attached the reducers to the wyes with self-tapping sheet metal screws.

It's a little longer and the material is a bit thinner than the competition, it does the job though.

Other uses.
I bought it to use as a funnel for loading my turbo burn barrel. Works good, made well with right size and fit.
