Pull Box Ladder Rungs

Step CAD Dwg Concast can add ladder rungs/steps to many of their larger pull boxes per customer specifications.  These steps are simple to field install too; just 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. These parts can be ordered under Concast part number STP-1.
