I'd like to have a hardwire solution to my front door, and unfortunately there is sideglass all the way around, sides and top. (So I could not pre-wire for a top or hinge mounted contact.) I do have complete access to the door threshold from the basement. Has anyone ever put one of these contacts on the bottom of the door, into the wooden threshold? I imagine the contact could get damaged from getting stepped on, but I could mount it as close to the edge as possible for the least amount of traffic. I have a 10 pack of the brown 3/8" contacts so they would at least blend in...
