As the price of metal continues to increase local authorities are seeing more manhole cover being stolen, which are then sold for scrap.
Clark-Drain’s solution for loading applications up to 35kN is the CLKS 452 dual-locking polypropylene inspection cover and frame for 450mm inspection chambers. By using the CLKS 452 dual locking cover and frame, local authorities can replace a steel cover with a lockable plastic version that offers the required performance in pedestrian areas, but is lockable and therefore not at risk from theft.
Another replacement cover is the Clark-Drain 701 H lockable cover for heavier duty highway applications and suitable for loadings up to 400kN. This ductile iron cover and frame is kitemarked to BS EN 124 D400kN and is Highways Agency HA104/02 Compliant. For security it has closed keyways and for long life performance is black bitumen coated.
Further alternative choices of cover are the Clark-Drain 704 H 600mm diameter hinged and locking round manhole cover frame and the 600mm diameter hinged and locking square frame. The company also offers the medium duty B125 lockable covers and lockable gully grates and frames.
