These rugged hanging dial scales are designed for heavy-duty use and are ideal scales for a variety of uses. The 8" (20cm) dial is easy-to-read and the dial mechanism is protected by a lens while the plastic housing eliminates dents and scratches, thereby enhancing long-term use and accuracy. The heavy-duty plated 4" (102mm) S-hook suspends commodities while weighing. Both net and gross weights are indicated fast and accurately with knife-blade pointers.
