High-Density Polyethylene
HDPE offers excellent impact strength, chemical resistance, and weatherability.
Duct bank spacers from Piedmont Plastics provide reliable support and alignment for underground electrical and communication conduit systems. Made from durable, non-conductive materials like HDPE, these spacers ensure consistent spacing, strength, and long-term performance. Ideal for utility, construction, and infrastructure projects, Piedmont offers local inventory, custom in-house routing, and expert material guidance.
Duct bank spacers are essential components in underground conduit systems, providing the structure and precision needed to support multiple electrical or communication lines in a secure and organized configuration. By maintaining consistent spacing between conduits, these spacers help prevent damage, interference, and misalignment during both installation and concrete encasement.
Engineered for strength, accuracy, and ease of installation, duct bank spacers made from performance plastics simplify the layout process and ensure that conduits remain properly aligned under load or environmental stress. Their non-conductive, corrosion-resistant construction makes them ideal for use in diverse conditions, from commercial and industrial sites to utility and transportation projects.
At Piedmont Plastics, we supply high-performance plastic duct bank spacers made from durable materials like HDPE and other industrial-grade plastics. Designed to withstand the demands of modern electrical and telecommunication infrastructure, our spacers deliver the reliability and long-term performance contractors and utility professionals depend on for every underground installation.


With over 100 years of combined product knowledge and industry experience, we are confident our plastics experts can help you find a solution for your application.
Piedmont Plastics offers duct bank spacers made from durable, non-conductive thermoplastics engineered for underground use.
While HDPE is the most common material used for duct bank spacers, other performance plastics such as PVC or ABS may be considered.
Whether you’re planning a new underground conduit system or replacing existing electrical infrastructure, choosing the right duct bank spacers can make a big difference in performance and installation efficiency. Below are answers to some of the most common questions about duct bank spacer materials, configurations, and where to buy them near you.
Most duct bank spacers are manufactured from HDPE (High-Density Polyethylene), though other performance plastics may also be used. These materials are non-conductive, lightweight, and resistant to moisture, chemicals, and corrosion, making them exceptionally well-suited for demanding underground environments.
Yes. Piedmont Plastics offers custom fabrication services, including cutting and routing to meet specific conduit sizes and spacing configurations. Our experts can help you design and produce spacers tailored to your exact project requirements.
Plastic spacers are lighter, corrosion-resistant, and non-conductive, making them easier to handle and safer for electrical installations. Unlike metal alternatives, they won’t rust or deteriorate in underground or wet conditions.
