Plain seated manhole covers are solid top access covers designed with a simple seating arrangement between the lid and frame, without any sealing gasket or locking system. The lid sits directly onto the frame, providing a straightforward and reliable access point to the chamber below.
These covers are commonly used in external installations where odour control or water tightness is not required. Typical applications include driveways, footpaths, service yards and general access areas where the priority is durability and ease of access rather than sealing performance.
The solid top design means the lid remains fully visible once installed and does not contain a recessed tray for infill materials. This makes installation simple and allows the cover to be lifted quickly for inspection and maintenance of the chamber.
Plain seated covers are available across a wide range of clear opening sizes and load ratings, making them suitable for both pedestrian and vehicle applications depending on the specification. Materials such as galvanised steel and ductile iron are commonly used to provide strength and long term performance in external environments.
These covers form part of the standard solid top range, where the focus is on durability and load performance rather than integration with surrounding surfaces or sealing requirements.
