Traditionally the installation of an electric strike involved cutting a small portion of the doorjamb to release the latchbolt of a circular lock from the pocket of the strike. This is an inconvenience in terms of the appearance of an opening, and it also exposes the mechanism of the latchbolt and keeper to any unauthorised users.
