Proto® J4944CF SAE Crowfoot Wrench, 1-3/8 in, 3/8 in Drive, 2-1/2 in OAL

• Used in hard to reach, restricted access situations where a standard wrench or ratchet cannot reach
• Anti-slip design open end 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
• Locking hole feature helps keep the crowfoot wrench engaged on the extension during use reducing downtime due to detachment of crowfoot in awkward spaces
