|Types of Locking|
Locks and Latches
British Standard Lock: BS3621
There are a number of different locks available on the market today which lock the door securely, but there are a few which bear the British Standard Kite Mark BS3621. This mark is applied to any lock which has undergone a vigorous testing procedure to make them particularly secure against any person trying to break the lock, and these tests include drilling, sawing and applying force to open the lock. They have minimum tolerances to pass but once these locks have passed the test, they are then able to wear the British Standard mark of approval. This mark is often essential with household insurance companies, who do specify that the final exit door locks must be to the BS3621 standard before they can offer any kind of cover.
Dead Bolt - Deadbolt
A dead bolt is used much the same as a latch, apart from it has no spring action and will not push back in; it requires just a turn of the key to lock and unlock. Often used to simply secure inside doors, or used in conjunction with a turn and release knob, the dead bolt is suited to toilet doors and the like.
Dead Lock - Deadlock
The dead lock is a lock which is opened and closed by only using the key, and it is a very simple and effective device mainly used with latches to add extra security. Deadlocks are often advised to be fitted towards the lower part of the door, and are ideal for extra security on any door with other locks fitted. These types of locks are available with the British standard mark which is generally specified by home insurance policies if being used as a main lock.
Sash Lock - Sashlocks
The sash lock is basically a deadlock and a latch built in together in one case, so the door will stay shut while offering a secure lock to boot. The sash locks are available in 3 lever or 5 lever options, with 5 lever being the safest, and some will have the added bonus of being up to the British standard BS3621. These locks have to be clearly marked, and this would be the type of lock to offer cover from insurance companies.
There are 2 main types of the latch; the standard and the heavy sprung latch. The heavy sprung option is generally used for handles needing that extra bit of lift on the return, such as heavy ironmongery handles. Most latches are used on a door that needs to be kept shut, but that do not require a lock; for example use in bedroom or bathroom doors. Most latches are operated with the use of a mortice knob or lever handle.
