STANLEY Infrastructure knows what you look for in a small mounted breaker, that’s why our MB series focuses on simplicity, easy maintenance, and powerful breaking performance. All MB breakers have only two moving parts – which means better performance and less frequent service intervals. At the lower end of the housing, we added steel reinforcement to not only protect the housing, but to protect the power cell and keep operators running longer. A superior valve design allows for a wider range of pressures and flows. lowering stress on components. Plus, the light tool weight contributes to a broader carrier range.
