Proto Refer to 157056 [4921MCF] Wrench Crowfoot 3/8 Drive 21mm 4921M

• 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 will be available.
• Typically used in lower torque applications.
• 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's arm or where the fastener is out of site.
• Locking hole on 3/8" drive crowfoot wrenches available on fractional openings 1" and larger.
