Built around the industry-leading Petzl Maestro, the RNR MGL 11mm Mainline Kit is a professional lowering and hauling system engineered for rescue teams, standby crews, rope access technicians, and industrial safety professionals.

The system is configured to support a wide range of mechanical advantage setups, including 3:1, 3:1 with change of direction, 5:1, and complex 5:1 hauling systems directly from the included components. By organizing critical rigging hardware, the Standby Pro Kit minimizes setup time, reduces gear sorting during high-stress operations, and improves overall scene efficiency.

At the core of the system is the Petzl Maestro, a highly efficient descender specifically designed for technical rescue applications involving heavy loads. The Maestro excels in both lowering and hauling operations and can be utilized as either a primary operating system or a back-up belay device. Its versatility allows rescuers to adapt quickly to changing rescue environments without needing to reconfigure major system components.

The ergonomic control handle and integrated braking system provide smooth, controlled descents, while the integrated progress-capture pulley with sealed ball bearings delivers exceptional hauling efficiency. Transitioning from lowering to hauling is immediate and seamless, eliminating the need for time-consuming load transfers. Additionally, the AUTO-LOCK function automatically secures the rope when the handle is released, enhancing operational safety during critical moments.

Whether responding to confined space incidents, industrial standby rescue operations, tower rescues, or technical rope scenarios, the MGL 11mm Mainline Kit was designed to provide rescuers with a streamlined, highly capable rigging solution that is ready for real-world deployment.
