OMNIFilter OW50-R6-05 Filter Housing Wrench by

MAKE FILTER CHANGES QUICK AND EASY - The right wrench turns a stuck, over-tightened housing sump loose in seconds, so changing your cartridge becomes a two-minute job instead of a knuckle-scraping struggle. FITS 10-INCH HEAVY DUTY HOUSINGS - Designed for Pentair OMNIFilter BF7, BF35 and PB35 Heavy Duty Big Blue housings, plus 10-inch heavy-duty housings from most other major brands. FREES TIGHT, JAMMED SUMPS - Wraps the housing sump for solid grip and leverage, helping you loosen a sump that pressure and time have sealed tight, without slipping or marring the housing. NOT FOR STANDARD OR SLIM HOUSINGS - Sized for 4.5-inch heavy-duty (Big Blue) sumps only; it will not fit slim 2.5-inch standard housings or U24-style housings, so match the wrench to your housing. KEEP THE RIGHT TOOL ON HAND - Store it with your spare cartridges so the correct wrench is always ready at change time; its durable build stands up to repeated use season after season.
