We didn't have a place to keep my dogs E-collar by the back door. So i made this holder. This does NOT allot charging while in the holder. Good fit, I used standard support. Bottom of the Collar holder was a little rough, might have ot paly with some settings are a perfect smooth finish. I was happy with it though. Also the holes for screws are 4mm, most dry wall mounts use screws that are 3.78mm.
