Lang RB-5 Ratcheting Box Wrench Set 5 Piece Inch

Product Description

The LANG RB-5 is a 5-piece ratcheting box end wrench set sized in inch measurements, designed for professional technicians who need fast, low-clearance fastener work without repositioning the wrench on every stroke. Each wrench features a 12-point ratcheting box end with a chrome-plated finish for corrosion resistance. The set ships in a vinyl roll pouch for organized storage and field transport. This set is well suited for HVAC, plumbing, and general mechanical work where access to standard hex fasteners is required with controlled torque motion.

This wrench set covers the five most common paired inch sizes used in residential and light commercial service work. It is appropriate for HVAC installation and service, plumbing rough-in and trim, electrical panel and equipment mounting, and pool equipment mechanical assembly. The ratcheting box end design is particularly useful in tight cabinet interiors or equipment compartments where a full swing arc is not possible. The vinyl roll storage keeps all five wrenches secure and accessible during service calls.

Installation Notes

This tool set is intended for use by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals. Always de-energize electrical equipment and shut off gas or water supply before using hand tools on system components. Select the correct wrench size to avoid rounding fastener heads. Inspect ratchet action before use and do not apply impact force to ratcheting mechanisms.
