Raised shroud: 
offers a greater 
level of security.

Flush shroud: 
decreased 
security.

2-1/16” to 2-1/4”).

e Security: 

the CL400 handle varies in security depending on the version 

and configuration. Handles supplied with a raised shroud provide a 
greater level of security than those with a flush shroud, however, it 
is important to note that the CL400 handle should not be installed in 

situations where a high level of security is required, e.g. external entry 

points or high security internal doorways.

Refer to the information printed on the Side Handle and Chassis boxes to 

ensure you have purchased a handle with the correct specifications for your situation.  

If the specifications are incorrect you will need to exchange the handle.

2. 

Component drawings have been provided. Please familiarise yourself with the components and check 

the package to ensure nothing is missing. Note: Components may vary slightly between configurations.

3. 

To ensure the handle latches accurately, it is essential that the door is adjusted for height and is 

parallel with the closing jamb when closed before installing the handle and striker.

4. 

This is a metric handle. Accurate measurements are shown in millimetres. Conversions to inches 

are approximate.

WARNING: THE STRIKER CONTAINS A STRONG MAGNET

IRON FILINGS - Magnets will attract shavings from iron or ferrous metals which may be hard to 

remove. Keep the striker a safe distance away from these materials.

DANGER FOR CHILDREN - Magnets may cause serious injury if swallowed. Keep out of reach of children. 

CRUSHING, BLISTERS AND CUTS - Fingers may become caught between magnets resulting in crushing, 

blisters or cuts.

BREAKING OR CHIPPING - It is possible that magnets could chip or shatter on contact with other hard 

materials, resulting in chips flying off at high speed into someone’s eye. Chips can also be very sharp - 

treat them as you would broken glass. 

MAGNETICALLY SENSITIVE ITEMS - Keep a safe distance between the magnet and all objects that can 

be damaged by magnetism (e.g. mechanical watches, pacemakers, cell phones etc.).

DISPOSAL - Magnets should be disposed of carefully and in accordance with your local regulations.
