The CLKS 452 is completely polypropylene plastic. It is square-to-round, making it suitable for round and square chambers. It also incorporates a 15degree tilt function.

It features a Dual Locking system, meaning you can twist the manhole cover into the chamber for a secure fit.

The 35kN loading means the 452 is suitable for applications where small trucks or large vans will drive over, but nothing greater. It is also suitable for pedestrian applications. Ideal uses include paving areas and driveways.

Probably the industry's most effective and safety conscious polypropylene inspection cover, the CD 456 has been developed in compliance with Part H of the Building Regulatiosn 2002. Part H refers to drainage and waste disposal and states: "small lightweight access covers will have to be secured (e.g. with screws) to deter unauthorised access."
