Got a tight spot where a regular wrench or socket just won't fit?

This Blackhawk by Proto crowfoot wrench is your solution.

It's a 21mm open-end wrench that attaches to a 3/8-inch drive ratchet or breaker bar.

It's perfect for plumbing lines, brake lines, or other low-to-medium torque applications on cars, motorcycles, or machinery.

The wrench has a full polished finish that resists corrosion and is easy to clean.

Part number is BCF-21M.

A must-have specialty tool for any serious DIYer or mechanic's toolbox to tackle those tricky, hard-to-reach fasteners.
