Rice Lake Weighing Systems 17 oz. Calibration Weight, Hook Style, Class 7, No Certficate, Cast Iron

Rice Lake Weighing Systems® cast iron weights undergo a phosphatizing process in which the metal is thoroughly cleaned and mildly etched to allow finish adhesion. The weights are then coated with a layer of chip-resistant paint which conforms to NIST Handbook 105-1 standards. This 2-step process ensures a long-lasting finish that greatly reduces the possibility of corrosion.
