So you just used the nylon as the box. I was thinking about doing the same out of PVC trim board & using that as the box/mounting serface. But it looks like Lowes may has a wall pack with motion sensors in stock locally.
The floor was just installed & ends at the slider. One of the door has a metal pin at the bottom but because the the steel bottom design it is not tight to the concrete. Should I use some wood/steel to move the pin in closer then drill a hole in the concrete for it? Or should I put a metal...
