Castors are necessary for furniture and equipment to be moved with ease. In order to make a larger object easily transportable, a castor is an undriven, compound wheel that is installed at the bottom of the object. High quality castors are designed to roll easily and smoothly while being strong and long-lasting. They are made from high-quality materials like steel or nylon and come in a variety of sizes and weight capacities. Castors are available in a number of alternatives such as fixed, swivel and specialty all designed to meet the specific needs of each application.
