Infinity Tools 6" Universal Flange

Needed a solid flange for my dust collection upgrade and this one fit the bill perfectly. The flat surface made it easy to drill mounting holes exactly where I wanted them.

Drilled four holes through the flange and it mounted flush to my dust collector cabinet without any flexing. The 4" to 6" transition feels solid, and the fit onto my hose was snug right out of the box.

Screwed this onto a plywood plenum to neck a 4" hose down to the 6" port and it sealed up with barely any leakage. The flange has enough flat surface area to drill clean mounting holes without cracking. Way sturdier plastic than the thin fittings I've bought before.
