Proto J4909MCF Open End Crowfoot Wrench 29/32 in

Product Description

The PROTO J4909MCF is an open end crowfoot wrench designed for use with 1/4-inch drive ratchets, extensions, and torque wrenches. The crowfoot head measures 29/32 inches in diameter and 1/4 inch thick, allowing access to fasteners in confined spaces where a standard wrench cannot seat. Overall length is 1-5/16 inches. The chrome-plated finish resists corrosion and simplifies cleanup in shop and field environments. This tool is built to ASME B107.21 and Federal Specification GGG-C-1507b, making it appropriate for professional and government contract work.

The J4909MCF is used by mechanics, millwrights, pipefitters, and maintenance technicians who need to apply torque to nuts or fittings in tight or obstructed locations. The low-profile 1/4-inch head thickness is well suited for shallow clearance situations such as plumbing fittings, HVAC component fasteners, and equipment panels where a box or open end wrench will not fit. It mates with standard 1/4-inch drive tooling.

Key Features

• 29/32-inch open end head for direct drive access in confined spaces
• 1/4-inch head thickness for shallow clearance fitment
• 1-5/16-inch overall length for compact reach
• Chrome-plated finish for corrosion resistance and easy cleaning
• Meets ASME B107.21 and Federal Spec GGG-C-1507b standards
• Covered by a limited lifetime warranty

Compatibility

Designed for use with standard 1/4-inch drive ratchets, extensions, and torque wrenches. Fits 29/32-inch fasteners in applications where clearance limits the use of conventional open end or box wrenches.

Installation Notes

Install and remove with 1/4-inch drive tooling only. Confirm the correct head size seats fully on the fastener before applying torque to avoid rounding. This tool does not substitute for a fully enclosed socket when full engagement is possible. Inspect for cracks or wear before each use per standard hand-tool safety practice.
