I bought an LED house number online. The instruction asks me to
- insert machine screws without head (grub screw, threaded rod) into the four machine screw holes on the back the LED box
- drill holes in the wall using 1/5" bit (I intend to try my 3/16" stucco bits, because I've never seen 1/5" drill bits)
- fill the holes with silicone caulk
- push the light box into the holes
This seems very unconventional. I was expecting to receive mounting plates that I can screw into the wall, not something like this.
So my question: Is this a valid way to mount something outdoors? Does it work on stucco (assuming I'll use stucco bits)? If not, what are my options?
