This 2 spoke handwheel from JBF National is manufactured from ultra-tough nylon with a matte black finish, features a molded in zinc plated steel hub, and is strong enough for just about any application. Its ergonomic design ensures a positive and comfortable grip even in oily conditions, and due to its nylon construction, is heat resistant up to 230 degrees Fahrenheit. To ensure that the continuous rotating action of this handwheel provides the highest level of grip and comfort, it comes with a high quality phenolic revolving handle.
