20 pound grip handle weight is ideal for calibrating scales that require a 20 lb calibration weight. These grip handle weights are made from cast iron, coated with a layer of chip-resistant paint which conforms to NIST Handbook 105-1 standards. The 20 lb grip weight's long-lasting finish greatly reduces the possibility of corrosion.

Many sign companies are now required to purchase a 20 pound certified weight (you'll need to purchase 12870C - 20 LB Grip Handle Weight WITH traceability certificate). Underwriters Laboratory requires strain relief testing on all U.L. listed signs with protruding electrical whips. They must be tested using a 20 lb. certified weight hanging from the wires for 1 minute.

We also offer a huge selection of Laboratory Calibration Weights and Calibration Mass Sets with Calibration certification and NIST Traceable Calibration for lab balances at www.calibrationweight.com
