RCBS

This Dial Caliper features hardened stainless steel construction with a matte, non-glare finish. It has four-way measurement capability: inside, outside, depth and step with a range of 0-6" with a 0.100" direct reading per revolution in 0.001" graduations. Shockproof movement allows for accurate measurements, and it is accurate to +/-0.001". A clear lens protects dial from dust and scratches. The slide may be locked in any position with thumb lock and the dial is easily zeroed with a lock screw to hold dial in position for precise measurements. A thumb wheel makes for easy opening and closing of the caliper. It comes with a fitted, hard plastic storage case.
