FP McCann manhole cover slabs are available in sizes DN900 to DN4000. They are heavy duty, reinforced concrete slabs and act as a platform to cap the manhole chmaber as well as to provide a base for any regulating brickwork prior to finishing with the manhole lid. They are also referred to as ‘reducing slabs’ as they reduce the access point opening size into the chamber. Landing slabs in sizes DN1500 to DN3000 are typically used in deeper manholes, limiting the depth to a maximum of 6 metres at any point, providing a safe landing or resting platform at such intervals.
