I needed to stack different-sized Gridfinity bins, but smaller ones wouldn’t sit securely on larger ones. My stairstep storage setup wasn’t working—so I designed a fix. The Gridfinity Universal Stacking Adapter lets you stack bins of different sizes while keeping them locked in place. A 2x2 can sit on a 2x4, a 2x3 on a 2x5, and more. It works as both a lid and a base, making storage more flexible. If you need to mix and match Gridfinity bins, this is the solution!
