Lang RB-3234M Box End Wrench 1 X 1-1/16 in 12 Point

Product Description

The LANG RB-3234M is a double-end ratcheting box end wrench designed for heavy-duty fastener work in trade and industrial applications. It features two box ends sized at 1 inch and 1-1/16 inches, each with a 12-point configuration for increased contact points on fastener heads. The chrome-plated steel construction resists corrosion and cleans easily. Reversing ratchet action on both ends allows for fast, efficient torquing and loosening without removing the wrench from the fastener, making it well-suited for tight or repetitive work in mechanical, HVAC, and plumbing service environments.

This wrench is intended for professional use in settings where large-diameter fasteners are common, including commercial HVAC equipment assembly, pipefitting, and heavy mechanical maintenance. The dual-size ends cover two closely related fastener sizes in a single tool, reducing the need to swap wrenches in confined spaces. Its ratcheting mechanism is particularly useful when swing arc is limited. Licensed tradespeople and maintenance mechanics working on equipment with 1-inch and 1-1/16-inch hardware will find this wrench a practical addition to a standard service set.

• 12-point box ends provide multiple engagement positions on fastener heads
• Ratcheting and reversing mechanism speeds up fastener work without removing the wrench
• Chrome-plated steel finish resists corrosion and simplifies cleaning
• Compact double-end format reduces tool count needed on the job

Compatibility

Designed for use with 1-inch and 1-1/16-inch hex fasteners in standard trade and industrial applications. No specific equipment or system compatibility was provided by the manufacturer for this part number.

Installation Notes

This wrench is used by licensed mechanics, HVAC technicians, plumbers, and pipefitters. Before servicing any equipment, de-energize electrical systems, shut off gas or fluid supply lines, and follow all applicable lockout/tagout procedures. Verify fastener size before applying torque to avoid rounding fastener heads. Do not use extension bars or pipe handles on this wrench beyond its designed capacity.
