“Very good quality, easy to use, but with a full size shelly e.g. a dimmer it can be quite tight in there for loop-in, loop-out, switch wiring and switch live to lights out. For some applications worked well, for some it was super tight, for some it was a non-starter and ended up with some Wago branded boxes.”
“Best junction box for this kind of application I have found. Nice and robust, and easy to drop all the parts into and clamp the cables after you've made sure everything works.”
“At last, something that accommodates smart switches! I've used these to accommodate not only Shelly devices, but other brands too, I even used them for general wiring (cable strain relief on Wago connected junctions. Very strong and sturdy and good price too.”
