Proto J4930CF Crowfoot Wrench 3/8 inch Drive 15/16 inch Open End

• 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) has patented locking grooves that help prevent the wrench from slipping off the fastener when turning.

• 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” drive crowfoot wrenches available on fractional openings 1” and larger.
