Manhole covers for highways

The DS6 is a square D400 product with a 600x600mm clear opening and can be used in D400 locations according to EN124-2015 standards.

It is one of the most commonly used sizes for highways. It has a uni-directional tread pattern to improve its anti-skid properties.

The DS6 does not have the ability to be made watertight, and if this was a requirement we would recommend you use the DM6 product. The DS6 can be supplied with or without a lock.
