Ladder Rungs

Ladder rungs/steps can be used in several applications, such as adding them to pull boxes.  These steps are simple to field install.  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.  The rungs are constructed of a copolymer polypropylene exterior with a 1/2" diameter Grade 60 steel reinforcement bar in the center. 

Order part number STP-2 for a ladder rung with a stainless steel core. Click here for specs.  These are great for applications that require frequent submersion.   Both versions meet ASTM-C478.
