Overview

Klein Tools built the 70591 as a compact 5.5 inch wrench that weighs just 0.49 pounds, sized for close-quarters work rather than heavy leverage.

At 5.5 inches, this sits on the smaller end for wrenches, sized for maneuvering in tight spots rather than heavy leverage work. Klein Tools built its reputation on tools for electricians and tradespeople, though this listing does not specify drive size or jaw opening.
