Manhole Covers > Highways > DR 60

The DR60 has a clear opening diameter of 600mm and can be used where there is high speed traffic, specifically for Group 4 applications as defined in the EN124:1994 standards. All the D400 range has been designed to resist the eccentric and horizontal forces that can rotated them and cause displacement of the cover. The DR range of covers will not spin or become dislodged from its frame as a result of traffic movement.

Personalisation of the covers can be added using logos. In addition the covers and frames can be made in different colours. All our composite D400 frames have a depth of 150mm, which is the minimum depth that SSC recommends for D400 covers. The D400 range can be supplied with or without a lock and can be made watertight using our specifically designed seal. It can also be retrofitted.
