If you are a HiTechPet door owner, and you live in a part of the country where there are seasons, you have probably experienced the occasion where the door opens and get stuck at the top of its travel.
This simple spring / stop prevents the door from getting stuck at the top of the track. Simply install in the door in place of one of the rubber door stops.
