Joe, This only works for enclosures that have the fan mounted inside. Yes, you place another filter spacer inside the box between the front panel and the fan. You can cut out the grill with wire cutters before installing. Longer screws will be required.
The Digikey part number is: CR212-ND. I am sure that an equivalent could be found as well.
