PASCO’s Mass and Hanger Set features polycarbonate mass hangers with steel posts, and “holed” masses that will not fall off the hanger. There are 27 weights in all ranging from 0.5 g to 100 g. Each mass has its value marked, and each hanger can hold approximately 250 g.
- The smaller masses have a unique design for better visibility.
- The hanger has a steel post for strong support.
- The hanger’s handle is notched making it easy to hang with thread.
