Rectangular Manhole Cover

The Standard Cast Iron Cover provides a durable and secure closure for drainage inspection chambers and sewer access points on residential or light commercial sites.

It integrates seamlessly into standard masonry or precast concrete chamber surrounds.

Built for the Job

Groundworkers and civil contractors utilize this drainage lid for finishing inspection pits in driveways, pathways, and garden areas. The heavy-duty casting resists warping under temperature fluctuations and maintains structural integrity against soil pressure. Its rectangular profile matches common brickwork dimensions, which simplifies the bedding process during the final stages of a drainage installation. The unit effectively seals off sewer gases and prevents debris from entering the pipe network.

• Installation over domestic inspection chambers for routine maintenance access.
