Description

This 300mm x 300mm recessed steel manhole cover provides a compact, sealed access point for tiled or screeded floor areas. It features a 40mm internal tray depth for infill and is secured with a double-seal system to block water and odour ingress. Manufactured from galvanised mild steel and rated for light to medium-duty use, this cover ensures a discreet and durable flush finish in both internal and external environments.

The unit offers a clear opening of 300mm x 300mm, with an overall frame size of 385mm x 385mm and a total depth of 58mm. This low-profile design is ideal for areas with limited build-up depth.
