A Long Cover for Wide Pits
Some pits are wider than they are deep, making a round cover unsuitable. This Square Cast Iron Manhole Cover is designed for long, wide pipe repair pits. A hinge connects the cover to the frame, preventing it from getting lost or separated. Made of ductile iron and finished with asphalt paint, it provides a durable cover for areas such as sidewalks and bike lanes.

Long Shape for Big Pits
With a cover size of 900×420 mm, this Square Cast Iron Manhole Cover is suitable for long repair pits. The frame measures 991×934×62 mm. Its hinged design allows one worker to open the cover with ease. The cast iron body is built to withstand foot traffic, and custom logos are available upon request.
