If you’re serious about your builds, a digital caliper is a must-have item. It lets you get the lengths of items like turnbuckles, shocks, and other settings just right. This caliper from Protek is perfect for your toolbox or workbench, thanks to its small 6-inch size. It’s made out of corrosion-resistant stainless steel and measurements are shown on an LCD display. You can choose from inch or metric measurements, and it has an auto-off feature to save battery life. It also comes with a protective plastic case and extra batteries.
