Lockable access covers

Fail safe locking systems

All our products have the ability to have a locking mechanism installed.

Lockable access covers not only improves site and location security and provides security against theft and malicious damage.

We supply a number of lockable access covers, we are happy to advice which would be more suitable for your needs.

The B125 range has a locking mechanism which has been designed to re-engage automatically when pushed back into the frame.

The C250 and D400 range has an ergonomically designed key which locks and unlocks the cover from the frame. 

The cover can never be left unlocked due to the way in which the key is removed from the locking mechanism, providing a failsafe system.

The frame design ensures that the surrounding concrete structure maintained in compression, which prevents displacement and cracking. Deep seating of the lockable access covers prevents any possibility of them being disturbed by impact forces. Continuous rather than three point seating eliminates wear and the SSC round covers have rotational restraint to prevent eccentric forces from causing displacement and wear.

B125 restraint device

Cover can be quickly unlocked using a standard key to BS497 or equivalent, and only requires unlocking from one end to allow ease of removal of cover from its frame. The system has been designed to allow automatic re-engagement of the restraining bolts when the cover is re-installed into its frame.
