Manhole Ladder / Manhole Ladder

Manhole Ladder

The manhole is the passage for a person to access into the underground. Usually, it’s used during the construction, but there’ s an inconvenience to set up the sign and ladder. So, to improve this difficulty, I suggest the Manhole ladder design which is combined a construction sign with a ladder for the more convenience during the construction.
