Electric Door Strike (image from bigasterisk.com) A better solution for door security hardware during a power outage is to use electric strikes. An electric strike is a mechanically operated strike that releases a door when the mechanical part is activated.
The latch bolt slides through a hole in a flat piece of metal called strike plate that is attached to and covering a hole in the door jamb. The idea is that for a door to latch properly, the latch bolt must make its way completely through the strike plate opening and rest snugly in the latch bolt hole. If it only does this just part of the way, your door is susceptible to opening on itâs own, entirely without your consent!
