Surface drainage and maintenance access to ensure smooth drainage
Our 4-inch manhole cover serves two main functions: First, it provides surface drainage, ensuring the smooth operation of the drainage system and reducing water accumulation. Second, it acts as a maintenance channel. Positioned above the drain outlet in atriums or flower beds, the 4-inch manhole cover functions as a safety mechanism when the drain outlet is blocked, making it easier to clear any obstructions. We recommend using an industrial vacuum cleaner for removal. This cover is especially suitable for atriums or flower beds with a fill height greater than 50cm, offering comprehensive protection for your drainage system.
