Proto J3114M Open End Wrench 14 Mm Double End

Product Description

The PROTO J3114M is a double-ended open end wrench sized at 14 mm, built for professional trade use in mechanical, HVAC, plumbing, and electrical service work. Forged from steel with a chrome-plated finish, the wrench features dual 15-degree and 60-degree head angles that allow access to fasteners in restricted spaces where a single-angle tool cannot reach. At 5.6 inches in length and 0.14 pounds, it is compact enough for tight installations without sacrificing leverage. The chrome finish resists corrosion and simplifies cleanup after service. This wrench meets GGG-W-636E standards and carries a lifetime warranty, making it a reliable long-term addition to any professional tool set.

The J3114M suits residential and commercial service applications wherever 14 mm fasteners are encountered. Common install scenarios include mechanical equipment panels, pipe fittings, electrical enclosures, and HVAC component hardware. The dual-angle head configuration is particularly useful when working around obstructions such as conduit, tubing, or adjacent components that limit swing arc. It is well suited for licensed tradespeople who need a compact, single-size wrench for targeted fastener work rather than a full set.

Installation Notes

This wrench is intended for use by qualified tradespeople including HVAC technicians, plumbers, electricians, and mechanical service professionals. Always de-energize electrical systems and shut off fluid or gas supplies before beginning any fastener work on live equipment. Use the appropriate head angle for the available swing arc to avoid rounding fastener flats. Inspect the wrench for damage before each use and do not use as a striking tool or apply extension bars to the handle.
