This is a mounting bracket to secure the
iSpring 100 Micron Reusable Sediment Water Filter House Water Filtration System to a wall. This is pretty handy especially if you are using PEX pipe which is somewhat flexible. It is easier to clean the filter screen if the filter is hard mounted to something.
Just place the filter in the base, place the clamps over the filter and screw through the clamps and base right into the wall or board. I used (4) 3" long sheetrock screws into a board. It's very secure.
NOTE: This will only fit if you use the internal 3/4" threads and not the external 1" threads for attaching your pipes.
