DM9
Manhole covers for highways
The DM9 is a new, longer rectangular D400 cover with a clear opening of 600x900mm. The DM9 is suitable for all DM400 locations according to EN124-2015 standards.
Personalisation of the covers can be added using logos. Additionally, 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 ThruBeam 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.
The DM9 has a flat, high-grip tread pattern giving it standout anti-skid properties. It can be made watertight and can be supplied with or without a lock.
