Striker Plate
A strike plate is a piece of hardware that works with a lock to keep a door secure. Strike plates are installed on the door frame and contains a hole which receives the spring loaded latch or bolt which comes out of the latch or lock.
There are a few generic type of strikers that work with commonly found latches which are listed below. Striker plates for mortice locks however are very specific to the lock they come with and cannot be bought separately.
Some common types of strikers are:
 | ‘D’ strikersSimple to remember as they are named after the shape. These are the most common striker plates used with latches. They are used on timber jambs. |
 | ‘T’ strikers(also named because of it’s shape) are used mainly for doors which are 38mm thick or more. They are most commonly used on steel frames (jambs) such as EzyJambs or commercial pressed metal door jambs. |
 | Round striker platesFound on doors that have pre-latched drive in latches. These are commonly supplied with the door and jamb and are common with off the shelf doors. Corinthian and Hume doors are some of the maufacturers that use these pre-hung systems. Based on the dimensions of these strikers, you cannot change to a different kind. This is beacuse there is too much patching required which is difficult to do. |
 | Electric strikesElectric strikes are used for digital access such as swipe cards, keypads and the like. These work by having a solenoid that blocks the tongue from moving. When an electric signal is sent, the solenoid pulls back and allows the tongue to be pushed open. These are commonly found on offices and entrance to apartment buildings. |
