The Polaris CT-500 body and rolls are made of cast and carefully machined high-strength special alloy aluminum. Gears are made of the strongest material available for this application, nylon or steel. Bushings are nylon and the remaining parts (except plastic gear covers and knobs) are machined steel. The table toppers are made of moisture-resistant Medex with a melamine surface. Metal surfaces are zinc plated or coated with a durable powder coat finish. Virtually no maintenance is required, and the simplicity of the design ensures that any repair ever needed will be quick and easy.
The Polaris CT-500 rolls slabs up to 22" wide and comes with a crank handle and two sheets of 36" long canvas.
