Introducing our high-quality 3" x 6" Manhole Covers, designed to meet all your monitoring needs. With product code MH36, these covers are made from fiberglass reinforced nylon, ensuring durability and longevity.

Featuring a bolt-in lid, these covers are secured with 0.25" stainless machine screws, providing a reliable and sturdy closure. The lid is equipped with a Buna-N-Oring and a threaded brass insert, further enhancing its strength. The lid is surrounded by a .125" wall HDPE skirt, adding an extra layer of protection.
