Overview
Measuring 6.25 inches with a 1.5 inch capacity, the Klein O5076 is a compact wrench from an established trade tool brand. Recent purchase activity points to steady demand for this model.
At 6.25 inches, this sits in the range of a standard adjustable or open-end wrench, small enough for one-handed use in most spaces. The 1.5 inch capacity likely refers to the maximum jaw opening or fastener size it accommodates, which is a useful reference point for matching it to your hardware. Klein's trade tool reputation typically means it is built for repeated professional use rather than occasional home projects.
