Pull Box Ladder Rungs
Concast can add ladder rungs/steps to many of their pull boxes. These steps are simple to field install. Pre-drill 1 inch diameter holes wherever you need the rungs, and then drive them in with a hammer until it is firmly seated in the pull box wall. These rungs are constructed of a copolymer polypropylene exterior with a 1/2" diameter Grade 60 steel reinforcement bar in the center.
