The type of manhole cover you buy depends on what you need to protect. Internal manhole lids are a good choice for many situations. If you have an in-ground swimming pool, trampoline, or hot tub, internal manhole covers can be a great solution.

They can also be used to protect underground water pumps or hot tubs and pools that aren’t in-ground but sit on top of concrete slabs surrounded by fencing.
