220–300mm Block Paving Recessed Manhole Cover 3.5 Tonne Square to Round

220–300mm Block Paving Recessed Manhole Cover 3.5 Tonne Square to Round

Description

This block paving recessed manhole cover is designed to convert a circular chamber opening into a square finish, allowing paving materials to be installed without cutting around a round lid. The recessed tray is filled with block paving, slabs or screed so the surface remains continuous.

The square-to-round adaptor can be trimmed to suit chamber openings between 220mm and 300mm diameter. This makes it suitable for retrofit work where chamber sizes are not consistent or where a standard square cover will not fit.

With a 3.5 tonne load rating, it is suitable for domestic driveways and areas with light vehicle traffic. The load is transferred through the frame into the surrounding ground, while the infill material remains non-structural.

Manufactured from polypropylene, the unit is lightweight, corrosion resistant and easy to handle. This cover is non-sealed and intended for external use only.

Why use a square to round cover instead of a standard square cover?

It avoids cutting paving around a circular opening and provides a cleaner, square finish in paved areas.
