The Milwaukee 6 In. Measuring Wheel was designed for extreme durability, increased ergonomics, and productivity. Constructed of reinforced aluminum frame and reinforced folding joints to withstand the toughest jobsite conditions. Durable locking pivot points help quickly fold the unit for transportation and storage. The pistol grip handle is designed to provide similar ergonomics to that of a power tool handle. These handles feature a top brake function that can be used to 'lock' the wheel and the reading, increasing accuracy. The Milwaukee 6 In. measuring wheel can be easily folded down to a compact 18 In. which allows for easier transport and versatility.
