The Arrow Lock BM11-BRL-4 Apartment Front Door Mortise Lock, as the name suggests, is well-suited for front door apartment style applications and settings. It has a latchbolt that is operated on either side by a lever, except when the outside lever is locked by stopworks, or when the deadbolt is projected. The deadbolt is operated by a key outside and a turnpiece inside. If you turn the inside lever, it will retract both the latchbolt and deadbolt simultaneously.
