Panic hardware usually has a carry-out specific mechanism that allows people to retract the latches, resulting in a push and pull bar.

Fire Exit Hardware

The Benefit of Panic Devices

In a crowded facility, when an emergency happens, people tend to panic and flood the nearest escape. Panic bars allow occupants to evacuate the building rapidly and quickly, reducing the danger of harm and confusion.


When we talk about panic devices, we know that they are highly beneficial. One of the significant benefits of this gadget is protection. They increase the safety of the building in case of a mishap.

The second important thing is the efficient working of such devices. In case of an emergency, an efficient device will be considered the priority. One of the significant reasons for its popularity is that it is fast and efficient in working. Moreover, people can fit an alarm to avoid unauthorized entry. They are entirely safe and best to install.


Another significant benefit of this gadget is affordability. Such locks are not very expensive and difficult to buy. Infact, any commercial owner can buy and install it on their doors.

Building owners do not want their doors to be left unlocked. These devices play a huge role in maintaining safety as well. It will allow the door to remain locked from the outside until it is opened by some internal force preventing unwanted entry. It is a quick and easy egress device installed on commercial doors, emergency locksmiths, and fire doors. This mechanism, also known as a crash bar, push bar, or panic mechanism, unlocks the door without using a key, twisting, levers, or any other unlocking techniques.

The working mechanism of push one is as follows. If anyone has to leave the building or pass to the door, push or press the button. When a person presses, the lock is temporarily released, which means that the Poe vast power is released when we push the button. It will cause the door to open automatically and allow free removal. In the end, the cord will detach, allowing people to open the door when needed.

  • Vertical Rod Exit Device
  • Concealed Vertical Rod
  • Side Latch Electric Panic Bar

Rim Panic Exit Device

A surface-mounted latch access control or bolt slips over the surface-mounted strike on this one. The most prevalent is the latch, which swings back at an angle as the bar or push pad is depressed. The latch is positioned on the center case’s front edge. Exterior trim with a lock cylinder will add to this. The deadbolt-style latch expands onto the strike when it is locked, reducing the gap between the bolt and the strike. Surface-mounted gadgets installed on the secured side of a door to allow free escape are rim exit devices. A latch has a more angled form than a Pullman bolt. The strike has a contoured design that boosts the locking strength of the Pullman bolt to increase locking capability.


A mortise lock body lies inside a slot formed in the side of the door in a mortise lock. The mortise exit device has a mortise lock positioned in the door pocket. The lock has a mortise lock. A mortise lock is not intended to be used as a panic exit device. When the push bar is pressed, the latch bolt is retracted by the spindle or tail shaft, allowing the door to swing out. Exterior trim with a lock cylinder will add to mortise lock exit devices.

Vertical Rod Exit Device

A vertical rod panic bar latch has the same lock as a horizontal panic bar, but instead of a standard horizontal lock, they contain locking and unlocking mechanisms at the bottom, and the top of the door is activated when the hardware is pressed. Vertical rod devices might have latches on the top and bottom of the door or just the top. The bottom latch is frequently undesirable since it can drag on the floor and cause damage.

The top latch engages a strike on the frame’s headpiece’s offside. When both doors are opened independently of one another, vertical rods are employed. Exit mechanisms for vertical rods are available in both concealed and surface versions. The rods link the top and bottom latches to the gadget’s push pad. Top and bottom rod vertical one is available, as well as top rod only.

Concealed Vertical Rod

This emergency hardware system is designed specifically for aluminum doors and includes unique rods to support the door frame’s hollow body. There are fewer chances of unwanted visitors exploiting the panic doors as entryways because the hardware will hide internally.

Side Latch Electric Panic Bar

This type of crash bar has a similar appearance. The locking mechanism is a heavy-duty side latch that latches onto the strike plate within the door frame. There are no vertical locking rods on it.

Double Door

A rim exit mechanism will be put on each pair of door leaves. Installing between the doors is the most secure and common technique to place rim escape devices on double doors. This mullion might be fixed or detachable. On either side of the mullion, the strikes for each rim device will mount.


We have discussed that exit devices are of great importance. They serve an essential role in ensuring people’s safety and security. People feel comfortable and secure inside the facility if there is a push bar door lock mechanism installed. An important thing that people need to know about winding up the discussion is that it is best to install such a lock if the property has a significant number of people.
