The feet on the ORI412A are threaded to be caster ready. Would they be the Marshall Pack-00050, or is that assuming too much? Someone here has to have screwed casters into one of these cabinets.
if you're looking to buy, I see them at Sweetwater for $75. They are more than helpful. Ask before you buy...
If you're looking for any caster that fits, I think the thread size is M10x25. That's what fit my Code212.
Thanks for the replies. I can confirm that the Marshall M-PACK-00050 is the correct caster set for the ORI412A. Just screw them in by hand until snug.
