Colorado Time Systems TP-60G 60" AquaGrip® Touchpad - The AquaGrip® Touchpad features the patented AquaGrip® texture over the foundation of a tough plastic backbone. AquaGrip® touchpads combine the best starting and turning surface available with the proven design that all Colorado Time Systems' touchpads have used for over forty years. They respond to a touch that's remarkably light – but provide a push-off that's thoroughly firm.
