The "Bridge Manhole Cover Holder" is a device that prevents the manhole cover from bouncing up. Due to its structure that does not block the drinking mouth of the manhole, it ensures drainage without clogging, and because it fixes the lower manhole and the eye plate, it can also prevent the upper manhole from scattering at the same time. For catch basins that are outside the scope of this product, we will manufacture compatible items from one piece based on our unique database, in conjunction with drawings and survey data (including contracts).
