Manhole wrenches are designed to safely lift and remove manhole covers and manhole covers.
They are inserted into the keyway of the hatch cover. The keyway is a slot or keyhole.
Hatch keys are usually sold in pairs because most hatches have two key slots, but single keys are also available.
Manhole covers may be too heavy to be lifted by one person. The lid must be lifted vertically and placed safely on the ground.
Hatch keys work by inserting into the lock groove. When the key is turned a quarter of a turn, it locks into place, allowing the lid to be lifted safely while holding it firmly. You can then move the manhole cover so that it cannot fall or slide back into the hole.
