How do I protect my shaft from unauthorised access?

Especially in the recent past, the need for security has increased significantly and is reflected in almost all situations in life. However, this is particularly evident where it is relatively easy to reach a large number of people. A simple example of this is the drinking water supply. It is not uncommon for the equipment in this sensitive area to be in a dilapidated state. In order to uncover possible weak points here, attempts to break into public facilities, including drinking water supply buildings, are repeatedly simulated.

Unauthorised persons should therefore not be given access to your manhole. An unauthorised opening of a manhole cover harbours many dangers for people and animals. Regardless of whether it was opened as a joke or wilfully destroyed, access to the manhole should be prevented. This also protects the water resource from contamination of all kinds. A security mortise lock is always useful for burglary prevention. It can be fitted with or without a profile cylinder.

For the installation of a manhole cover in particularly sensitive areas, such as Ex zone 1, in which an explosive atmosphere can occasionally form, a further special option is available: A design in accordance with DIN 1239:2018-4, with a test certificate for burglar-resistant properties in resistance class RC3 (burglar resistance is regulated by DIN EN 1627; in accordance with the requirements of DVGW W 1050 - Property protection of water supply systems). Taking into account violent offender groups, available tools and attack time, six different resistance classes, RC1 to RC6, are categorised. Manhole covers that have been successfully tested for resistance class RC3 by an external testing institute set new standards in burglar resistance for manhole covers. This means you are doing your best to ensure reliable security for your manhole or building.
