The Empire 150mm Professional Measuring Wheel is designed for commercial use, and is ideal for use in tight spaces where maneuverability is important. With a 1/3rd folding handle, carry bag, and total weight of just over 1 kilo, this Measuring Wheel is also perfect for both indoor and outdoor measurements in areas that are inaccessible by vehicles. The true-zero indicator shows the exact starting point for measurements, while the trigger brake prevents free wheel spinning when the wheel is not in contact with the surface to be measured.
