It’s Gridfinity, but on a 52mm grid to match the Sortimo System used and advocated for by Adam Savage. Sort - Finity. (Grid-Timo didn’t sound as nice)

I’ve felt the 42mm bins are slightly too small for my needs but the 52mm bins seem just right. Zack launched Gridfinity on a 42mm grid ‘’ why 42mm? well… why not”.

I also looked at the techtronics Milwaukee and RYOBI systems. Packout is Based on a double 52mm grid (104x104) while Ryobi leans on the 42mm grid. So take your pick of homeowner grid vs a contractor grid.
