- 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
- 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 arm or where the fastener is out of site
- ASME B107.21
