600 x 600mm Composite B125 Solid Top Manhole Cover

The Clark Drain CD 265/SF is a 600 x 600mm composite solid top manhole cover supplied with a galvanised steel frame. It is designed for chambers serving street lighting, traffic signals and similar utility networks where a durable non-metallic cover is preferred.

The composite lid offers lower weight than comparable metal covers, helping with handling during installation and maintenance. It is also resistant to rust, corrosion, chemicals and deformation, making it suitable for exposed outdoor environments and damp ground conditions.

This model is rated to B125 and tested to BS EN 124-1:2015, making it suitable for pedestrian areas and light vehicle traffic locations where the specification permits. The galvanised steel frame provides structural support and long-term durability in paved, concrete, tarmac or verge installations.

Integrated lifting keyholes accept Clark Drain CD 553 or CD 553L lifting keys, while fitted stainless steel locking screws help secure the lid in position. Debris-reducing keyhole caps are included to keep access points cleaner in service.

A common mistake is selecting composite covers by size alone. Always confirm the required loading class, chamber opening and site application before ordering.
