Review on Effortless Mobility: Acrux7 M10X25 Shopping Trolley Casters for Easy Maneuverability by Lild Zimmerly

Excellent videos. Well made and fits my granite top bar perfectly. But unfortunately, trying to find the right size T-nuts to screw in turned out to be a total failure. They appear to be metric sized which means the threads will not work on a 3/8" tee. It goes roughly one thread and then just jams. I figured if I ordered 10mm t-nuts it would work but they are too small. Nothing on this list will give you the exact size you need for a tee nut. Very frustrating. There is a nut on the screw but I don't know what size it is.
