Security as standard

Vault™ D400 manhole covers

Vault secure access covers exceed the requirements of LPCB level 3 version 8, the stainless steel lock provides rugged durability and reliability.

Designed and manufactured to meet the requirements of BS EN 124:2015 and includes safety features such as a sequential opening locking system and stops which secure the covers in upright position for safe and simple operation.


Vault manhole covers are specifically designed to secure valuable underground equipment, such as motorway communications systems.

The Vault ranges safety features include a sequential opening locking system - meaning only one lock is required- and stops which fix the covers in a upright position when hinged, preventing accidental closures.

Years of exceptional performance

Our Highway D400 covers are still operating at full capacity after three and a half years of being subjected to high levels of HGV traffic. Meaning the organisation can focus solely on new work, rather than being distracted by manhole covers that have failed prematurely and need fixing or, in some cases, reinstalling.
