The Fowler 53-620-010 is a height transfer and squareness gauge with a measurement range of 0 to 7.5", a large fine adjustment knob, a hand-operated feed slider with fine-adjustment wheel in base, a swivel clamp, and a rust-resistant, satin chrome finish. A large fine adjustment knob in the base isolates the column and indicator (sold separately) from heat and hand pressure to provide precise control. A swivel clamp anchors the swivel and indicator for added accuracy. The rear surface of the gauge has a reference to square against a master for checking squareness. The gauge comes with the 7.5" post, indicator rod, and clamp.

Height gauges, sometimes referred to as gages, are precision measuring instruments that travel on a vertical column (also called the beam) to measure and/or mark the vertical distance from the base of an object in fine units. The vertical position of the gauge and its attached pointer are changed by turning a calibrated screw, or one or more feed wheels. Recorded rotations are read from a scale, a dial, counters, and/or an electronic display. A screw clamp holds the pointer to the gauge. The pointer is typically sharpened to act as a scriber, and can be used to mark a position on a workpiece by scratching its surface. On compatible units, the scriber may be replaced by an electronic touch-signal probe. Height gauges are typically used in manufacturing, machining, and mechanical engineering.

The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
