Mobile chrome shelving for storing or displaying items These four-tier shelf trolleys have an attractive zinc chromate finish and are mobile on four x 125mm diameter rubber-tyred swivel castors 2 braked. Each wheel features a buffer to protect walls and doorways from damage when the trolley is being transported. The large 240kg weight limit when uniformly distributed over the trolley makes it ideal for a range of applications. The shelves and handle can be adjusted on 25mm intervals to best suit the height of products being stored or the user.
