FW10F is a Universal Water Filter Wrench designed for slim countertop or inline housings. Can be used on countertop or under sink water filter housings that carry standard 10" long by 2.5" wide water filters.
How to use Universal Water Filter Wrench.
Slide the opening over the filter housing, until a good fit has been achieved. Rotate the wrench until it grabs the edges on a housing. Push harder to loosen the canister.
Do NOT use the wrench to secure the canister after filter has been replaced, doing so will damage the o-rings. Always only hand tighten the housing!
