This is a square cover and frame unit designed for use with 350mm access chambers in underground drainage systems. Manufactured from black uPVC, it offers a lightweight yet robust solution for closing off and securing manhole openings on site.
Suitable for new installations or maintenance work, this cover and frame provides safe access for inspection chambers and helps prevent the ingress of debris. Often used in civils and drainage projects, it is compatible with typical underground fittings and is sized for practical handling during setting and removal operations.
