Overview

RIDGID's 31100 wrench comes to this listing with no dimensions, weight or material spec attached, just the brand and model number to identify it.

Where most tool listings lean on a length or jaw-opening figure to describe fit and reach, this one has none, so anyone comparing sizes against another wrench will need to check RIDGID's own spec sheet first.
