Proto J4956CF Open End Crowfoot Wrench 1-3/4 Inch

Product Description

The PROTO J4956CF is a 1-3/4 inch open end crowfoot wrench designed for accessing fasteners in tight or restricted spaces where a standard wrench cannot reach. The crowfoot head attaches to a standard 3/8 inch drive extension or ratchet, expanding the usefulness of an existing drive set without requiring a dedicated handle. With a head diameter of 2.9 inches and a head thickness of 0.38 inches, the profile stays low enough to work in confined areas. The chrome-plated finish resists corrosion and makes cleanup straightforward. This tool is suited for mechanics, plumbers, HVAC technicians, and other trades who regularly work around piping, fittings, and bracketed assemblies.

This crowfoot wrench is appropriate for general mechanical and trade service work in residential and commercial settings. Typical applications include tightening or loosening hex nuts on pipe fittings, hydraulic lines, HVAC refrigerant lines, and similar assemblies where swing clearance is limited. It is sized at 1-3/4 inch, making it relevant for larger fasteners and nuts common in commercial plumbing and mechanical piping systems. The open end design allows the wrench to slide onto a fastener from the side, useful when the end of the fastener is not accessible.
