A digital gauge option for Hercules stressing jacks is accurate, rugged, and built to withstand the harsh environment of a prestressing yard, according to Prestress Supply. Unlike analog gauges, the digital gauge cannot be shock loaded out of calibration. To make calibration easier, the load data can be stored in a laptop and reloaded into the jack at any time. The LCD readout screen is bright, can be easily read in direct sunlight, and designed to resist fading or discoloration due to prolonged sun exposure. The gauge is available on both the Hercules Model “B” and Model “C” jacks. Retrofit kits are also available to convert existing jacks in the field over to digital readouts. — Prestress Supply Inc., 800/328-8036, 800/282-7321 (in Florida);
