Recessed, square to round cover allows block paving and slabs to be laid over access covers to give a neat top edge design. Square frame significantly reduces installation time and paving up to the cover is quick and easy. Paving stones can be cut to suit the profile of the frame whilst the circular opening, with universal spigot, locates directly onto the chamber riser. Recessed tray is able to receive up to 40mm of concrete or floor finish infill. Angled inner lid aids cover removal. For loading up to 10 tonnes.
