Exit devices are basically designed to be placed onto the secure side of swinging out doors. They limit the access while also offering free exit. The exit device were quite effective in solving the problem of people being crushed against the doors. This mainly happened because people didn’t have prior knowledge on how to open doors or when to unlock and open the door. A number of manufacturers are still offering the more conventional cross bar design. Precision Hardware exit devices are quite popular in the market. These devices have evolved quite a bit and have integrated rail-style design that uses forward mounted push pad.
There are three most commonly used types of exit devices — rim exit devices, mortise and vertical rod.
Rim exit devices come with a surface-mounted latch or with a bolt that can slide over the strike. The more common latch used is the one that swings back at an angle as the push pad or bar is depressed. The latch is placed at the center case’s front edge. A dead latching mechanism limits the latch from getting forcibly retracted so as not to allow unauthorized access. Rim exit devices can be facilitated by using exterior trim consisting of a lock cylinder.
The mortise lock style exit tool implements a mortise lock generally that is used without a deadbolt mounted in the pocket of the door. This lock is a major component of the exit device. A regular mortise lock is not designed to function as an exit device. When we press the push bar, the tail shaft or the spindle rotates retracting the latch bolt. This essentially permits the door to swing out.
Vertical rod style devices are present in the concealed or surface variants. The rods join the device's push pad to both top and bottom latches. These special exit devices can be tweaked as top and bottom rod, or simply top rod, commonly referred to as Less Bottom Rod (LBR). LBR exit device set up are usually for the interiors or doors present within a secured area.
