Electric strike

There are many manufacturers of electric strikes, and there are many things that have to be considered when buying one, i.e., type of jamb, type of locking hardware, whether one requires fail-secure, fail-safe or hold-open function, length of the latch, depth of jamb, voltage requirements and the length of the faceplate.

Electric strikes can be differentiated in a number of ways, frame type it can be installed in, duty (continuous or intermittent), and which variety of locking mechanism on the door it can work with.

The four most common locking mechanisms concerned with electric strikes are Cylindrical, Deadbolt, Mortise, and Rim Panic Exit Devices.

Cylindrical electric strikes are generally the cheapest due to their use in residential markets.

Rim exit devices (panic bars or crash bars) are required in many buildings as a 'single motion' means of egress and electric strikes used in these situations are typically different from electric strikes for other situations.
