3 Lever
A 3 lever mortice deadlock is suited for use on lower security applications such as internal doors or sheds. If you are looking for a deadlock for an external door, we would suggest browsing our British Standard, 5 Lever or detainer deadlocks which all offer a higher grade of security.
Euro profile deadlocks are also a popular choice of commercial properties where the locks must be changed frequently (such as a block of flats) or a Master Keyed system is in use.
