Innovative Lightweight, High-Strength Alternative to Cast Iron
Bison Boxes feature a cast iron rim and lid complemented by high-strength, thick-walled ABS plastic top and bottom sections. Cast iron rims, lids, and top sections are suitable for roadway installations and are H20 load rated. Once the cast iron rim or top section is embedded in the concrete or asphalt, the roadway takes the loading, takes the loading, not the plastic components below.
Bison CIP Boxes blend high-strength, lightweight ABS plastic for the bottom section with a standard cast iron lid and top section. This combination offers a lighter, more cost effective solution while retaining the locating benefits of cast iron.
