Well Made

Well made holders with brass thread inserts in heavy plastic cases. Nice heavy painted brackets to fasten to the wall. Easily the best of the large filters holders,

Big blue 4.5”x20”

Installed one so far. Had to use longer bolts on the bracket because the holes are out of spec for the bolts that were sent. I used 5/16 lag screws that were longer and they hold well. The 5 micron filter didn’t fit gray and I initially had a leak but repositioned and everything is fine so far.
