Remember when you had maximum precision in your measurements Give your dial indicator the support it needs with the WEN Magnetic Base. This handy tool provides a much-needed mount for your precision dial indicator, keeping it elevated and adjustable during operation. Calculate runout and calibrate test equipment with ease by mounting to either the lug or the mount hole of your indicator. Our 3-arm system pivots, bends, and locks in a full 360°, reaching up to 14.5 in. H, All 3 arms are controlled by the quick-release lock knob for fast and accurate adjustments. Simply install the dial indicator using the method of your choice and turn on the magnetic base. This creates over 175 lbs. of magnetic force, allowing you to attach the 2.5 in. x 2 in. base to any ferrous metal surface. With forces of that magnitude, there will be no wobbling and sliding here. After that, adjust and pivot the arm into position and start calibrating. When you're done, simply turn off the power switch, disengaging the magnetic base for simple removal and repositioning. Although this unit was designed with the WEN Dial Indicator (models 10702, 10703) in mind, its universal 3/8 in. mounting hole is compatible with the majority of dial indicators on the market. And, because it's a WEN product, your magnetic base comes backed by a two-year warranty, a nationwide network of skilled service technicians, and a friendly customer help line, all to make sure you remember WEN.
