Description
Scale/Balance for comparing weighted number blocks; useful in teaching math comparison and pre-algebra. Scale has suction cup feet (20mm diameter), but the "legs" can be bolted to a more substantial base (of your choosing). Assembled with M3x5 (top/arm) and M3x8 (btm/legs) -- the holes are essentially self-tapping.
