VGK, Inc manufactures an Oil Free, Stainless Steel Meat Trolley. No more trolley oil, no carcass contamination due to rail dust/black specks! Which means no more carcass trimming from rail dust/black specks. Trolley cleaning with no hazardous chemicals. Minimal trolley repair since there's no metal-to-metal contact from rail to wheel. Our Radius edge Stainless rail completes the Oil-Free potential.
