Reversible Disabled Bathroom Lockset (Radar Type)

This is an alternative bathroom mortice lock and handle set for disabled toilet doors. It is a direct replacement for RADAR and NKS locks but it is not handed, so the latch can be reversed.

It features a latchbolt which is operated by special NKS key and lever handle, which are included in the kit. NKS and RADAR keys are compatible and can be used interchangeably.

A RADAR key (which stands for The Royal Association for Disability and Rehabilitation), also known as an NKS key, is a blue, red or silver-coloured key that opens more than 10,000 disabled toilets across the UK. RADAR keys are used by some 400 local authorities to allow disabled people access to locked, accessible toilets, while providing protection against vandalism and misuse.

The Royal Association for Disability and Rehabilitation, which is now Disability Rights UK, created the National Key Scheme (NKS) and the first RADAR locks were fitted in 1981 to help keep accessible toilets free and clean for disabled people.

Before RADAR locks were introduced, many establishments locked the accessible toilet themselves which meant that disabled people could only use the toilet on request. There were also cases where the key couldn’t be located by the staff member, or the person who had it wasn’t on duty that day. Fortunately, the introduction of the NKS meant disabled people could now use the toilet without having to ask someone if they could be let in.

In line with a number of other mortice locks, these locks feature a silver lock case but they have unique measurements that identify them from other mortice locks. Please refer to the line drawing for details.

This bathroom mortice lock is available in satin chrome finish only.

The deadlatch throws 14mm. If higher security is required, or the ability to lock the bathroom door from the outside, we’d recommend a euro case mortice lock with key and turn euro cylinder.

From the inside, the deadlatch is locked on closing the door and unlocked by the lever handle. From the outside, the deadlatch can be unlocked using a NKS or RADAR key.

This lock is supplied with a striking plate in a finish which matches the lock and a set of lever handles.

Suitable for use on most internal wooden doors. These locks are not handed and can be used on doors hinged on the left or right, which open inwards or outwards.

Supplied with 1 nickel plated, steel keys as standard. Extra keys are available from stock.

These locks do not need to be keyed alike as they all operate on the same key as standard.

We stock a range of associated parts to these locks, including key blanks. Please select the products you require from the associated products on this page.

These locks are not suitable for use on a fire door.

 

Mortice lever locks (sometimes called mortise locks) are commonly fitted to wooden doors but can also be found used in steel, aluminium, and composite doors. They are locked from both the inside and outside with the key which throws the deadbolt. By definition, a mortice lock is fitted (“morticed”) within the door, rather than being fitted to the face or surface of it.

There are multiple types of lever lock in use in the UK. Dead locks (mortice dead locks) are operated by a key only whereas sash locks (mortice sash locks) feature a dead bolt and a latch which is operated by a handle (often a lever handle). Both lever locks with throw the dead bolt into a strike plate. The strike plate on sash locks also accepts the sprung loaded reversible latch.

Lever mortice deadlocks can be used for fitting to front or back doors and to internal doors and external doors, but we’d always recommend fitting a British Standard BS3621 product to external doors for maximum security. You should also check with the houseowner’s insurer’s requirements on both residential properties and commercial properties. You may find lever locks fitted to commercial properties but cylinder lock cases operated by a cylinder or pin tumbler lock are more common mortice locks fitted in commercial environments.

Lever mortice door locks are commonly used for internal doors too. These tend to be 3 lever mortice locks where the requirements for security and burglary prevention are lower.

When replacing an existing lever mortice lock, you may find that your replacement mortice lock is larger than the one that you are replacing. This may be because you are improving security, such as upgrading to a lock with thicker, anti-drill hard steel plates or because the forend length, forend width or the design of the lock has changed. The hole for the lock can normally be made larger with a hammer and chisel. This can also be the case for strikes, which may have changed design.

When fitting a lever mortice lock to new timber doors, we’d recommend using Souber’s DBB morticer for quick results. You can find the DBB1 morticer here: https://www.duffells.com/souber-db
