That's what I just did! i decided to take the "leader", and the "holder" (Swenglish for sleeve, and plug-in caster) off from the cabinet, and exchange them for 50 mm diameter lockable rubber wheels. Don't understand why I didn't come to think of that solution right away, cause I had put rubber wheels on my old 2x15? Well, sometimes the memory bank is som full of sh-t that it takes some time for it to begin to work on all cylinders (that's gb for the modern man. I'm not).
So, gather round me people, and read my lips: Hope you all have a really nice weekend?
