The Black Diamond 12 in. Measuring Wheel with Locking Stand is designed for fast, reliable distance measuring on the jobsite, featuring a lightweight 42 1/2 in. aluminum shaft for steady control while you roll. With a measurement range of 0–10,000 ft., it’s well suited for checking long runs, laying out work areas, and estimating distances for planning and material takeoffs. The locking stand keeps the wheel upright and secure when you pause, making it easy to set down between measurements and get back to work without fuss.
