If you work with scales or testing equipment, you know how important accurate weights are. This Rice Lake 5-pound cast iron test weight is built to professional standards with that classic grip handle that makes it easy to move around. It meets ASTM E617 Class 7 specifications, which is perfect for rough weighing operations in labs or industrial settings. The painted finish is seriously tough - chip-resistant and corrosion-resistant so it'll last through years of use. What's cool is that it conforms to NIST Handbook standards, so you know you're getting reliable accuracy. The grip handle isn't just for looks either - it makes handling so much easier when you're calibrating scales or testing force-measuring equipment. Rice Lake has been making quality weighing equipment since 1946, and they know their stuff. This isn't some cheap import - it's proper American-made quality that'll give you consistent results year after year. Whether you're in a school lab, industrial facility, or doing quality control work, this weight delivers the precision you need without breaking the bank.
