Trench box

This is a trench box designed to protect workers when working in trenches.
This is a unique model that uses a skinned mesh to be able to adjust the height, length and width.
They can be joined together to form longer protection.
It can also be lifted using any of the cranes that I or Shane Phillips have built.
Since crossbars experience collisions, excavators should also be able to pull or lift them from these points.
