This customer installation clearly shows the advantages of KEEPING the current light switch cover plate and ONLY installing a device that mounts UNDER the light switch cover.
As you can see in the pictures below, this light switch cover is very ornate and trying to make all of the different shapes and sizes of wall switch plates would be a HUGE task. Plus BearMar’s current manufacturing process really would not lend itself to a smooth glossy surface.
Check out these customer pics of the dog leash hanger from BearMar. (you can find the wall mount dog leash holder on Amazon or Walmart if you want to buy from a site you’ve heard of before).
