Abstract

A lock includes a deadbolt assembly having a deadbolt and a deadbolt actuator. The lock also includes a latch assembly discrete from the deadbolt assembly. The latch assembly includes a shoot bolt and a shoot bolt actuator. A blocking element may block actuation of the shoot bolt from an unlocked position to a locked position when the deadbolt is in a retracted position. Alternatively or additionally, the blocking element may block actuation of the shoot bolt from a locked position to an unlocked position when the deadbolt is in an extended position.
