450mm Block Paving Recessed Manhole Cover 10 Tonne Square to Round

450mm Block Paving Recessed Manhole Cover 10 Tonne Square to Round

Description

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

With a 10 tonne load rating, it is suitable for domestic driveways and areas with light vehicle traffic. The galvanised steel tray provides structural strength, while the surrounding frame transfers loads into the ground rather than through the infill material.

The square to round design removes the need for shaping paving around circular chambers, improving finish quality and reducing installation time. The tray can also be rotated within the frame to align with the paving pattern during installation.

This cover is non-sealed and intended for external applications only.
