A solution for every scenario
Highway D400 Surface Boxes
Our D400 Highway surface box is suitable to be used in the carriageway. Featuring standard Highway features such as, indexed covers, enlarged frame corners and is 70+ PSRV tested.
Our Highway D400 covers are still operating at full capacity after three and a half years of being subjected to high levels of HGV traffic. Meaning the organisation can focus solely on new work, rather than being distracted by manhole covers that have failed prematurely and need fixing or, in some cases, reinstalling.
