This simple tape gauge provides reliable reference points when taking inside or outside measurements. Made of durable plastic, it has a clear acrylic plate with a hairline sighting mark set exactly five inches from the rear of the gauge and one inch from the front. This lets you easily add a whole number to or subtract it from the measurement shown on the tape instead of the usual fractional dimension noted on your tape case. It can be used with any regular tape measure by clipping the tape measure to the gauge and extending the tape under the heightadjustable hairline marker.
Measures 6"x1-7/8"x1-7/8". A convenient tool for accurate measurements.
