• Crowfoot wrenches are used in hard-to-reach, restricted access situations where a standard wrench or ratchet cannot reach
• Anti-slip design open end (ASD)
• The arched surfaces are designed to spread the contact forces over a greater area and they keep the loads off the corners of the fastener which helps prevent fastener rounding
• Broad size range ensures the right tool for the application
• Full polish finish provides corrosion resistance and easy-to-clean surfaces
• Has patented locking grooves that help prevent the wrench from slipping off the fastener when turning
• Locking hole feature helps keep the crowfoot wrench engaged on the extension during use reducing downtime due to detachment of crowfoot in awkward spaces
• Use with locking extensions to reach into spaces too small for a mechanic's arm or where the fastener is out of site
• 12 point allows for fine indexing
• Helping to improve speed and access
