Service caster has great service and great product. Work smoothly. Same size mounting plate. Used these move my monster truck jumping ramp.

When my mat goes in the maker it just slides itself to make it work without any troubles. With the wheels, it moves easier and the vacuum can get under it. Now when i need the occasional tool, it rolls out without a fuss.

I put 4 wheels on it and as soon as i turned it over and the weight on wheels 2 wheels broke off.
