My home (under construction) will be getting spray foam insulation in a month or so. I want to run some smurf tube conduit in a few exterior walls before the house is insulated. All the low voltage "boxes" I've seen that accept smurf tube adapters are open on the back and sides. My guess is I will end up with the LV boxes at least partially encapsulated in the foam, and may have some foam that expands up into the smurf tubes.
Are there any boxes that are more like the blue plastic line voltage boxes that will accept a 3/4" or 1" smurf tube adapter? I guess I can tape the tube openings to keep foam out of the tubes, but I would still have to cut out the foam around the LV boxes afterwards. I'm getting open cell spray foam, so cutting it out probably won't be too bad, but it seems like a closed box would be a lot better.
Thanks,
Ira
