Legal-for-Trade Grip-Handle Test Weights with Calibration Certificate
To confirm accurate calibration of legal-for-trade scales, these test weights come with a certificate of calibration traceable to ASTM that states they’ve passed a test for accuracy. They have a handle for easy carrying and are used to calibrate legal-for-trade scales. All are marked with their weight.

Grip-Handle Test Weights with Calibration Certificate
A certificate of calibration traceable to NIST states that these weights have passed a test for accuracy. They have a handle for easy carrying and are used to calibrate scales. All are marked with their weight.
Grip-Handle Test Weights
A handle makes it easy to move these test weights. They are marked with their weight.
Weight Bags
Hold down equipment and balance loads with these bags. Made with Cordura nylon, they’re dustproof, waterproof, and puncture resistant. The seams are double-stitched to form a tight seal.
Bags filled with sand are an economical choice, but their weight will change slightly over time as the sand dries out. Orange bags are easy to spot, even when visibility is poor.
Bags filled with stainless steel shot have tight weight tolerances, so they can also be used as test weights.

Hanging Weight Bags
Use the adjustable strap to suspend these bags from rigging, booms, and other equipment that you need to balance. You can attach them anywhere: unhook the strap from the bag, wrap it around your equipment, then clip it back onto the bag. Their bottom is flat, so you can also set these bags upright to weigh down equipment. Made from Cordura nylon, the cover is dustproof, waterproof, and puncture resistant—you can use these bags indoors or outdoors. Double-stitched seams form a tight seal to keep the sand from leaking out.
