D400 & E600 manhole cover locking options

Locking options

Recognising the importance of controlled access in maintaining the integrity and safety of civil engineering projects, we offer advanced locking options for all D400 and E600 ranges of manhole covers. These options are designed to deter unauthorised access while being resistant to the respective (BS EN 124) Group traffic and common UK highway contaminants, thereby ensuring the longevity and reliability of the installations.

Factory-fitted screw fasteners

At the core of Wrekin’s optional D400 & E600 security features are the factory-fitted screw fasteners. These fasteners are engineered to be robust and durable, providing a simple yet effective barrier against unauthorised chamber entry. The design of these fasteners allows for easy operation with conventional tools, ensuring that only authorised personnel can access the installations without undue difficulty.

Alternative fasteners for enhanced security

For projects requiring an elevated level of security, Wrekin offer the option to upgrade to other forms of fastener, on request. Such additional options can provide an additional layer of security, making it significantly more challenging for unauthorised individuals to gain access to a chamber. Employing advanced fasteners is particularly recommended for sensitive or high-security areas where the risk of tampering or unauthorised entry needs to be minimised.
