What materials are duct bank spacers made from?

Most duct bank spacers are made from HDPE, a non-conductive, corrosion-resistant plastic ideal for underground use. Other performance plastics such as PVC or ABS (Acrylonitrile Butadiene Styrene) may also be used, depending on project requirements. These materials provide excellent strength, durability, and electrical insulation for long-term performance in buried conduit systems.
