The loading dock kit is a simple and economical solution for creating a visual barrier in a variety of retail and professional environments. To use the loading dock kit, simply put the carabiner on the magnet ring, put the chain on the carabiner, and stick the magnetic end on any metallic surface. The bright yellow 2-inch chain makes this kit a great choice for loading docks where OSHA requires only a visual barrier and is useful for warning those in and around stairwells or other openings where a person could fall and be injured. The loading dock kit can also be assembled in seconds to mark off aisles in retail stores, warehouses, or distribution centers.
