The Monument 1010L is manufactured from a single piece of malleable iron for greater durability and strength. It has a tee shaped handle for greater torque and added leverage and a 'D' shaped end that fits snug in to most manhole covers for easy and secured lifting.
The shape of these keys can be changed to fit in small key holes by using a file or hacksaw.
The Monument 1010L has a 100mm (4 in) wide handle and a 125mm (5 in) shaft.
