The LANG RBM-1517M is a double-end ratcheting box end wrench sized for 15 mm and 17 mm fasteners. Built from chrome-plated steel, it delivers a clean, corrosion-resistant finish suitable for shop and field use. The 12-point box profile engages hex fasteners at 30-degree increments, reducing the arc swing needed in tight quarters. The reversing ratchet mechanism allows the tech to change drive direction without removing the wrench from the fastener, speeding up repetitive fastener work. Licensed HVAC techs, plumbers, electricians, and general service professionals will find this wrench useful on equipment panels, piping connections, and mechanical assemblies where these metric fastener sizes appear.
This wrench is suited for both residential and light commercial service applications. The 15 mm and 17 mm sizing covers a wide range of metric fasteners commonly found on HVAC equipment, refrigeration units, pumps, and piping assemblies. Its double-end configuration means two common metric sizes are available in a single tool, reducing the number of tools a technician needs to carry on a service call. The ratcheting and reversing functions make it especially productive in confined spaces where full-rotation access is not available.
Designed as a general-purpose metric ratcheting box end wrench for use with 15 mm and 17 mm hex fasteners on mechanical, HVAC, plumbing, and electrical equipment.
This wrench is used by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals. Always de-energize or shut down equipment before loosening fasteners on panels, covers, or pressurized assemblies. Inspect the ratchet mechanism for proper engagement before applying torque to critical fasteners. Do not use extensions or cheater bars on box end wrenches not rated for extended-handle loads.
