D400 Manhole Covers

Wrekin’s range of secure access covers exceed the requirements of LPCB level 3 version 8. Version 8 represents a significant step forward over version 7, providing assessors with new, more heavy duty attack tools. The patented stainless steel lock provides rugged durability and reliability.

Designed and manufactured to meet the enhanced requirements of Highway England’s HA 104/09 specification. Our hinged Vault range of access covers also exceed BS EN 124-2 D400 requirements and include patented safety features, including a sequential opening locking system and stops which fix the covers in a unique, simple to use, upright position for safe and simple operation.
