A sander that is not only capable but thrives in multiple-shift environments.

The Cantek SR43DA 43″ Widebelt Sander combines a solid machine frame with unparalleled machine features resulting in superior sanding quality & reliability. The dual sanding heads result in less passes through the sander resulting in increased efficiency and throughput.
