All of the crates they currently sell in Q2 2024 fit and lock into the SidioSkate 3.0 . The wheels are great but you have to make a couple of improvements for them to work as intended.

What you get in the package is 4 wheels, 16 screws & 16 locking nuts that need to be at least finger tight to hold onto the base. The screws that come with it are a bit too long and will interfere with the wheels and won't be able to freely rotate 360°.

My first picture shows how close the screw comes in contact with the wheels. What you can't see is I have my own spacers installed but they give it the room it needs to freely rotate. I supplied the exact dimension of spacer needed for them to work. Maybe Sidio can supply some or just get smaller screws. Hopefully I'm the only one with this issue. Other than that they work great on concrete and carpet!

Also they don't use standard caster sizes for the wheels so you can't upgrade them. Here is the Dimensions for the wheels:
