Proto 1/2" Drive Wobble Extension 10" J5463W-SBD

Proto's professional-grade 1-3/8 inch SAE tether-ready box end crowfoot wrench engineered for high-precision industrial maintenance and assembly. Featuring a 1/2 inch drive and a 12-point configuration, this tool is designed to provide maximum accessibility and engagement on large fasteners in confined spaces while ensuring an essential safety layer for elevated work. The integrated Positive Control System requires a separate tool for attachment or removal, ensuring the wrench cannot be accidentally detached—a critical safety feature for preventing dropped objects in "at-height" environments. Built with a heat-treated alloy and a durable chrome finish, this crowfoot wrench is designed to resist wear and corrosion throughout a long service life.
