ASSA Replacement Cam Arms for Locker and Cabinet Locks
Total Locker Service supplies replacement ASSA cam arms for compatible 8450, 10450, 391350A and 492831A locker locks. These components fit to the rear of the lock and engage with the locker or cabinet frame to secure the door.
Cam arms are available in different lengths, shapes and offsets. Selecting the correct replacement requires matching the existing cam profile, fixing arrangement and locking position. Similar-looking components are not necessarily interchangeable.
ASSA Cam Arms for Compatible Lock Models
The range includes replacement cam arms for selected locks in the following ASSA product families:
- ASSA 8450: Replacement cam arms for compatible ASSA cam locks.
- ASSA 10450: Alternative cam profiles for compatible ASSA locking arrangements.
- ASSA 391350A: Cam arms for compatible short ASSA locker hasps used on doors up to 16 mm thick.
- ASSA 492831A: Cam arms for compatible longer ASSA locker hasps used on doors up to 22 mm thick.
These references identify compatible lock families rather than guaranteeing that every cam profile fits every lock. Always confirm the individual cam arm before ordering.
How to Choose the Correct ASSA Cam Arm
Select the required cam reference from the product options above. References such as Cam05, Cam06 and Cam69 identify different cam profiles. Compare the selected component with the original fitting and the ASSA cam arm specification sheet .
The most important identification details are the cam length, mounting or fixing arrangement, bend or offset and the position where the cam engages behind the locker frame. A cam that fits the lock spindle may still be unsuitable if its dimensions prevent the door from locking correctly.
Where the original cam is missing, measure the available clearance between the lock and frame. The Specification section provides additional guidance on identifying and measuring replacement parts.
Replacing Damaged or Missing ASSA Lock Cam Arms
Replacing a worn, bent, damaged or missing cam arm may restore the operation of an existing ASSA locker lock without replacing the complete lock body.
This can be useful when maintaining locker installations in schools, workplaces, leisure centres and other facilities where existing locks remain serviceable.
Before fitting a replacement, check that the lock mechanism operates correctly and that the new cam engages securely with the frame. Do not bend or modify a replacement arm unless modification is specifically permitted for that component.
If the lock body, spindle or internal mechanism is damaged, a complete replacement may be more appropriate. Explore our replacement locker locks or browse ASSA locker locks and components .
ASSA Cam Arms for Padlock Hasp Locks
Selected ASSA cam arms are also used with compatible padlock-operated hasp locks. The rear catch must match the locker door and frame arrangement to provide proper engagement when the hasp is secured.
For replacement hasp bodies and information about the 16 mm and 22 mm versions, visit our ASSA locker hasps page.
Ordering Replacement ASSA Cam Arms
Before ordering, identify the existing cam reference or compare the component with the manufacturer drawings. If you cannot identify the correct profile, provide clear photographs of the lock and cam arm, together with the relevant measurements.

ASSA Cam Arm Specification and Compatibility
ASSA cam arms are replacement components fitted to the rear of compatible ASSA cam and hasp locks. The cam rotates when the lock is operated, engaging behind the locker door frame, cabinet return or locking point to secure the door.
Cam arms are available for ASSA lock references 8450, 10450, 391350A and 492831A. The correct component must be selected using the lock reference, existing cam shape, fixing arrangement and the dimensions required for the installation. Cam arms that appear similar may have different offsets, lengths or profiles and should not be assumed to be interchangeable.
Before ordering, check the number marked on the existing ASSA lock and compare the original cam arm with the options shown in the ASSA cam arm specification sheet . Clear photographs and measurements can also help identify the correct replacement.

Information Required to Identify an ASSA Cam Arm
For reliable identification, provide the full ASSA lock reference together with a clear photograph of the front and rear of the lock. Measure the overall cam length, the distance from the fixing point to the end of the cam and any bend or offset in the arm. It is also useful to show how the cam engages with the locker or cabinet frame.

ASSA Cam Arm FAQs
Which ASSA locks are these cam arms designed for?
These replacement cam arms are intended for compatible ASSA lock references 8450, 10450, 391350A and 492831A. The exact cam must still be selected by comparing the lock reference, fixing arrangement, profile and dimensions.
How do I identify the correct ASSA cam arm?
Check the reference marked on the ASSA lock and compare the original cam with the options in the ASSA cam arm specification sheet . Photographs and measurements of the existing cam can help confirm the correct part.
Are ASSA cam arms interchangeable?
Not necessarily. Cam arms can differ in length, offset, shape and fixing arrangement. A cam that fits the lock spindle may still fail to engage correctly with the locker or cabinet frame, so compatibility should be confirmed before ordering.
What measurements are needed for a replacement cam arm?
Measure the overall cam length, the distance from the mounting point to the end of the arm and any bend or offset. Also check the fixing hole or spindle arrangement and the position where the cam engages behind the frame.
Can I identify an ASSA cam arm from a photograph?
A photograph can assist identification, particularly when it shows the lock reference, rear fixing and full cam profile. Include a ruler or dimensions in the image because visual comparison alone may not confirm the correct size.
Do I need to replace the complete ASSA lock?
A complete lock may not be required when the existing lock operates correctly and only the cam arm is damaged, missing or unsuitable. Where the lock body, key mechanism or rear fixing is damaged, view the available replacement locker locks or request assistance identifying the complete assembly.
Can Total Locker Service help identify an unknown ASSA component?
Yes. Provide photographs of the lock and cam arm, the ASSA reference and the relevant measurements. For component identification, repairs and maintenance, see our locker service and repair solutions .
Where can I find other ASSA locks and replacement parts?
The wider ASSA range is available from our ASSA locks and components page. General locker components, including handles, hinges and locking parts, can be found in the locker replacement parts section.
