Lang RB-810M Box End Wrench 1/4 X 5/16 in 6 Point Ratcheting

Product Description

The LANG RB-810M is a double-end ratcheting box end wrench sized at 1/4 inch and 5/16 inch. It is built from steel with a chrome-plated finish and features a 6-point box profile on both ends. The ratcheting mechanism allows a technician to drive fasteners without removing and repositioning the wrench on each stroke, which speeds up work in confined spaces. Weighing 0.175 pounds, it is a lightweight hand tool suited for tight quarters. Licensed mechanics, HVAC technicians, plumbers, and electricians reach for this style of wrench when working around equipment panels, control boxes, and piping connections where swing angle is limited.

The RB-810M is appropriate for both residential and light commercial service work. It fits standard SAE fasteners in the 1/4 inch and 5/16 inch sizes commonly found on access panels, equipment enclosures, condensate traps, electrical knockout hardware, and similar small fasteners encountered during routine maintenance and installation work. The double-end design eliminates the need to carry two separate wrenches for these two adjacent sizes.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Always confirm the correct size before applying torque to avoid rounding fastener heads. When working on energized electrical equipment or pressurized systems, follow applicable NEC, IPC, or IFGC lockout and shutoff procedures before use. Inspect the ratcheting mechanism periodically to confirm it engages and holds correctly before applying load.
