Lang RBM-1113M Box End Wrench 11x13mm 6-pt Ratcheting

Product Description

The LANG RBM-1113M is a double-end ratcheting box end wrench sized at 11 mm and 13 mm, built from steel for durability in demanding service environments. The 6-point box profile grips fastener flats squarely, reducing the risk of rounding under torque. The ratcheting mechanism allows continuous drive without breaking contact with the fastener, making it practical in tight or confined spaces. At 0.325 pounds, it is lightweight enough for extended use on the bench or in the field. HVAC technicians, plumbers, electricians, and general maintenance professionals will find both metric sizes frequently useful on equipment fasteners, panel hardware, and mechanical assemblies.

This wrench is suited for residential and commercial service work where metric fasteners in the 11 mm and 13 mm range appear regularly. Typical applications include equipment access panel hardware, motor mounting bolts, pipe flange fasteners, and electrical enclosure hardware. The double-end configuration provides two sizes in a single tool, reducing the number of hand tools required on a service call. The ratcheting box end design is especially effective in restricted spaces where a standard open-end or combination wrench cannot complete a full swing arc.

Installation Notes

This wrench is suitable for use by any licensed trade professional working with metric fasteners. Always ensure the box end is fully seated on the fastener before applying torque to prevent slipping. Power down or de-energize equipment before using hand tools in proximity to energized components. Inspect the ratcheting mechanism periodically for wear or debris that could affect engagement reliability.
