Rice Lake Slotted Interlocking Cast Iron Calibration Weights

Calibration weights for calibrating force gauges, load cells, torque instruments and more. Use these slotted weights with hanger weights for suspending weights.  Rice Lake cast iron weights undergo a special phosphatizing process in which the metal is thoroughly cleaned and mildly etched to allow exceptional finish adhesion. The weights are then coated with a layer of chip-resistant paint which conforms to NIST Handbook 105-1 standards. This two-step process ensures a long-lasting finish that greatly reduces the possibility of corrosion.  Part # Weight ASTM Class Dimensions 12837 0.5 lb 7 3-3/4" Dia x 7/16" H x 9/16" Slot Width 12842 1 lb 7 5" Dia x 7/16" H x 9/16" Slot Width 12848 2 lb 7 5" Dia x 3/4" H x 9/16" Slot Width 12852 5 lb 7 5-1/8" Dia x 1-1/4" H x 9/16" Slot Width 12826 10 lb 7 6-1/8" Dia x 1-9/16" H x 3/4" Slot Width 12831 20 lb 6 8-1/8" Dia x 1-7/8" H x 3/4" Slot Width 12856 50 lb 6 10-1/2" Dia x 2-1/2" H x 9/16" Slot Width
