These are the original US General 6” casters from my brand new 56” USG Roller Cabinet. I prefer my working top to be lower to match my 42” roller cabinet. This set comes with 2 Fixed and 2 Swivel casters. These can be fitted to your 27” or 44” roller cabinets to make them the same height as a 56” or 72” cabinets without dealing with risers. You reuse your bolts. These were removed from my cart as soon as I got them off the truck. US General PN: 604999 and 605000
