  • 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 will be available
  • Typically used in lower torque applications
  • Full polish finish provides corrosion resistance and easy to clean surfaces
  • Locking hole on 3/8 in drive crowfoot wrenches available on fractional openings 1 in and larger
  • Use with locking extensions to reach into spaces too small for a mechanic's arm or where the fastener is out of site
  • Locking hole feature helps keep the crowfoot wrench engaged on the extension during use reducing downtime due to detachment of crowfoot in awkward spaces
