Is there any measurements for the it to go on the [n-filter](https://www.gbfans.com/wiki/equipment/proton-pack/n-filter) like how wide it is and how far from the top of it should it be placed. Thanks to anybody who can answer. ---

It’s either 4mm or 5mm automotive pinstripe. Maybe someone else can confirm the size. Start it about 1/4" from the weld. ---

I think its 4mm. It just barely touches the holes on the [N-filter](https://www.gbfans.com/wiki/equipment/proton-pack/n-filter). A light tickle, if you will 😉
