The KNIPEX Tools Improved 12" Pliers Wrench features an increased jaw capacity from 2-1/2" to 2-3/8". The increased jaw capacity is due to the addition of two more adjustment positions, which gives the 12" Pliers Wrench a total of 24 different push-button adjustment positions. Other features include a lighter weight, recessed areas for a better grip, laser-etched markings in both metric and imperial, as well as reliable catching of the hinge bolt to prevent unintentional shifting of the tool. It's available in a chrome plated finish (No. 86 03 300) and black atramentized finish (No. 86 01 300).
