Proto J3119M Double End Open End Wrench 19 Mm

Product Description

The PROTO J3119M is a double-end open end wrench sized at 19 mm, built for professional trade use in mechanical, HVAC, plumbing, and industrial service applications. Constructed from steel with a chrome-plated finish, this wrench delivers corrosion resistance and long service life in demanding shop and field environments. The double-ended head configuration features a 15-degree and 60-degree head angle, giving technicians two offset options in a single tool for working in tight or obstructed clearances. At 0.24 pounds, it is light enough for one-handed use without sacrificing durability.

This wrench is suited for residential and commercial service work where metric fasteners are standard. The 19 mm jaw size covers common bolt and nut sizes found on HVAC equipment, refrigeration components, piping assemblies, and mechanical systems. The dual-angle head design makes it practical in confined spaces where a straight-pull approach is not possible. It ships individually and is appropriate for technicians who require a single metric wrench to complement an existing set or replace a worn tool.
