Two-sided manhole step

Abstract

A two-sided manhole step. The step includes a first step surface and a second step surface. Lugs extend from ends of the first and second step surfaces. The lugs help to prevent individuals from sliding off the manhole step, regardless of whether the step is installed with the first step surface or second step surface facing upwards.
