A mortice lock can play a huge part in the security of your home or business. There are many different types and sizes available on the market and at Door Furniture Direct we will do our best to ensure you have all of the information needed to help you make the right decision about which mortice lock you should choose. A 5 lever mortice lock to BS3621 standard offers more security than a 3 lever mortice lock because of the increased number of key combinations available and greater protection from picking or drilling the lock together with a stronger locking bolt with a longer throw. 3 lever mortice locks are generally fitted to internal doors.
5 Lever Mortice Locks
A five lever mortice deadlock would typically be fitted to a wooden door that does not have door handles. It would normally be used in conjunction with a nightlatch which allows the door to be open and closed without being deadlocked. Once the mortice key is turned, the door is locked and cannot be opened unless unlocked using the key. Again, a 5 lever deadlock is more secure than a 3 lever deadlock. A 5 lever sashlock offers the same deadbolt feature but also has a latch option and so should be fitted when using door handles with a keyhole in the back plate. When choosing 5 lever mortice locks for external doors you should always check with your insurance providers as they often specify that you fit British Standard mortice locks that meet the requirements of BS3621 with provides higher security.
Bathroom Mortice Locks
Internal doors around the home are generally fitted with 3 lever mortice locks apart from bathrooms and toilets which could use either a bathroom mortice lock or a bathroom deadbolt. A bathroom mortice lock would be the best option if using bathroom handles with a snib and release function on the back plate, whereas a bathroom deadbolt is a great option when using lever on rose handles or door knobs and a separate turn and release.
