15-Piece Crowfoot Wrench Sets, Inch, 3/8 in Drive

Anti-Slip Design open end (ASD) has patented locking grooves that help prevent the wrench from slipping off the fastener when turning. Crowfoot wrenches are used in hard to reach, restricted access situations where a standard wrench or ratchet cannot reach. Full polish finish provides corrosion resistance and easy-to-clean surfaces. Locking hole feature helps keep the crowfoot wrench engaged on the extension during use, reducing downtime due to detachment of crowfoot in awkward spaces.
