A safety lock and access key for doors that otherwise need to remain locked comprising a lock body containing a spring biased catch extending from one end of the body to engage in a keep of the door frame, a lever for moving the catch into the body to unlock the door, and a tool for unlocking locked doors.

An exemplary damper module is configured for use with a latchbolt assembly, and generally includes a mounting bracket, a first slowing mechanism, and a second slowing mechanism. The latchbolt assembly generally includes a drive member, a latchbolt, and a retractor connected between the drive member and the latchbolt. Each of the slowing mechanisms is independently operable to slow the extension speed of the latchbolt. The first slowing mechanism includes a rack gear and a rotary damper including a pinion gear. The rack gear is configured to be mounted to the drive member, and the rotary damper is mounted to the mounting bracket. The second slowing mechanism includes a slowing arm and a biasing member engaged with the slowing arm. The slowing arm is movably mounted to the mounting bracket and is configured to engage the retractor.

Door systems and door hardware components are described herein, along with methods of installing the door systems and components. The door systems include a bottom spacer that racks the door system in an opening in which the door system is being installed to facilitate proper spacing of the door after removal of the bottom spacer.

A vehicle mitigation system includes a first portable barrier, a second portable barrier; and a gate assembly. The gate assembly includes a beam pivotally attached to the first portable barrier. The beam is capable of rotating between a closed position and an open position such that the beam remains substantially parallel to a surface on which the first and second portable barriers are positioned. The gate assembly includes at least one arrestor cable attached between the first portable barrier and the second portable barrier such that the arrestor cable spans a distance between the first and second portable barriers.

A vehicle mitigation system comprises a first portable barrier, a second portable barrier, and a gate assembly comprising a beam. The gate assembly is pivotally attached to the second portable barrier, and the beam is capable of rotating between a closed position and an open position. The beam in the closed position is substantially parallel to a surface on which the first and second portable barriers are positioned. The beam in the open position is no longer parallel to the surface and has been raised vertically away from the surface. The gate assembly has at least one arrestor cable attached between the first portable barrier and the second portable barrier such that the arrestor cable spans a distance between the first and second portable barriers.

A latch bolt with a bolt head that is removably mounted on a latch tail through the use of a reversibility assembly, such as bolt head adjustment mechanism, or the like. The reversibility assembly may comprise one or more locking members (e.g., within the bolt head, the latch tail, tail plate, and/or independent from the other components of the latch bolt) that allow the bolt head and/or the latch tail to be removed, rotated, and reassembled without opening the case of the mortise lock. The bolt head may comprise an anti-friction latch that is configured to pivot within the flanges of the bolt head in a way that maintains contact between the anti-friction lock and the strike plate.
