Lang RB-3436M Ratcheting Box End Wrench 1-1/16 X 1-1/8 in 12 Pt

Product Description

The LANG RB-3436M is a double-end ratcheting box end wrench sized at 1-1/16 inches and 1-1/8 inches. It features a 12-point box profile on both ends and a reversing ratchet mechanism that allows fastener engagement without removing and repositioning the wrench on each stroke. The chrome-plated steel construction resists corrosion and cleans easily. At 1.37 pounds, it provides solid feel without excess bulk. This wrench is a standard hand tool used by HVAC technicians, plumbers, electricians, and general trade professionals who work with hex fasteners in confined or repetitive-turn applications.

This wrench is suited for residential and commercial service work where access is limited and continuous repositioning slows the job. The ratcheting action is especially useful when torqueing or loosening fasteners in tight mechanical spaces, such as equipment panels, pipe flanges, and electrical enclosures. The dual-end sizing covers two common fastener dimensions in a single tool, reducing the number of wrenches a technician needs to carry. It is appropriate for general mechanical service across HVAC, plumbing, and electrical trades.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Before use in any service application, de-energize electrical systems, shut off gas or water supply as applicable, and follow all relevant safety codes including NEC, IFGC, and IPC where required. Inspect the ratchet mechanism for smooth engagement before applying load to critical fasteners. Do not use extension bars or pipe over the handle to increase leverage beyond the tool's intended capacity.
