USED BRS Wrench for RO/Media Canisters

These are very handy to have around and are made of strong plastic to last just as long as your Reverse Osmosis system. Wrench for 2.5" Canisters (most common) - This is the same wrench that is supplied with all BRS RO/DI systems and is by far the most common size for residential reverse osmosis systems and works with almost all canisters that use 2.5" filters.
