This PVC cover and adjustable frame is designed for use with 300mm manhole inspection chambers in underground drainage systems. Finished in a red-brown colour, it offers a practical solution for securely covering access points in a variety of installations.
The product is commonly used by groundworkers and drainage contractors when building or maintaining below-ground drainage networks. The adjustable frame allows for alignment during fitting, helping to achieve a flush finish with the surrounding surface in both new build and refurbishment work.
