Magnet ring carabiner kit
November 27, 2016
The Magnet Ring/Carabiner Kit includes two magnet rings and two carabiners. The rings contain powerful rare-earth neodymium magnets, which will adhere to any metal surface. Combined with the carabiners and the company’s 2-inch plastic chain (not included), it creates a quick way to restrict access to areas. It is ideal for closing aisles between shelving units in warehouses and distribution centers, checkout lanes in retail stores, or machinery in manufacturing facilities.
