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.Fits most standard housings 10 in. × 2.5 in.Inside diameter of 4.8 in.Replaces standard plastic SW–2 wrenchFits Pentek #150295Fits American Plumber 152037, American Plumber ww34Fits Culligan HF-150, HF-160, HF-360, HF-365, Culligan #150295-27, Culligan #01019185Also fits Ametek, Axeon, Dupont WFPF38001C, Everpure 150259, Omni OB1 series A and more
