The Superb Wrench filter housing metal wrench is made to replace the plastic wrench that breaks when removing a filter housing unit. The wrench is made out of 7 gauge zinc-plated steel that will not break, bend or strip the housing unit when stuck . The handle is long for extra leverage, and a directional arrow is printed on the rubberized handle with the words "loosen" to prevent turning in the wrong direction. It makes the Superb Wrench virtually indestructible while making filter change easy.
Inside diameter of 4.6 in.
