Magnum 4 Inch Pocket-Sized Fractional/SAE/Metric Digital Caliper (1058)

Sometimes a standard six-inch measuring tool is simply too long to fit into cramped engine bays or tight machine setups. This compact 4-inch digital caliper slips easily into a shop apron pocket and navigates confined spaces without interference. It brings the full functionality of three-way readouts—metric, decimal, and fractional—into a smaller, highly maneuverable precision instrument.
