Steel ShieldsSteel Manhole Boxes are used to help secure the trench walls created for the construction of manholes on job sites. They eliminate the possibility of your trench walls caving in and create a safe working environment for manhole installation. There are doors on most manhole boxes to tie pipes into manholes without having to remove the manhole box. Complete your entire manhole installation with the safety of a protected trench!
