One of the largest industrial supplier companies in the United States. They deal mainly with industrial and workman supplies like lightings, plumbing, hand tools, machining supplies, accessories, hydraulics, pumps, power tools, welding equipment, testing and safety equipments and so on. If you work in an industrial environment, they will definitely sell something which you will need. Oh,they sell home improvement items as well. One of the reasons why they are so popular is because they provide on-site support for most of the products they sell, instead of relying on the manufacturer. This probably sets them apart from other retailers. They claim that their technical support personnels are extensively trained in the products which they sell. They have over 18,500 employees and they are headquartered in Illinois.
