How many come in the pack?

Just one comes in the pack. We bought 3 they are very nice, and clean so you don’t have just a hole in the floor.

Would it work for still air box? Keeping air out of a sealed box while running a cable through the box for fungi work

It is normally used on raised floor for cable outlet, and fixed by screws. So if you want to use it on sealed box, need to test it.
