Its single-sided L-shaped shelves and side compartments help keep items stable and accessible during use. Made from carbon steel and cold rolled steel, it supports heavy loads while maintaining a compact footprint. Silent swivel casters with two locking wheels provide smooth movement and secure positioning. The powder-coated finish adds durability for everyday use.
