“A great size vented box for remote sensors and a radio. Easy to cut and robust.
The only downside is its harder to detach the cover if you are fixing the backplate to a wall.”
“Not a bad-looking room sensor enclosure for temperature and/or humidity. Fits a standard UK wall box, and has mounting holes on the base, I didn't use them, but not a problem to add your own and Aroldite in place.”
