Duct Bank Spacers
Durable HDPE Conduit Solutions from Port Plastics
Support Underground Conduits & Accelerate Installation
Keep your underground conduits aligned, secure and on schedule with Port Plastics duct bank spacers. Our recycled-HDPE spacers, hold conduits firmly during concrete pours and reduce installation time dramatically. Manufactured locally in Phoenix and shipped nationwide, they deliver strength, durability and value right where you need it.
Overview
Modern utility, telecommunications and data systems run through miles of underground conduit. Duct bank spacers keep those conduits level, evenly spaced and free of kinks or gaps that could let moisture, dirt or concrete creep in. Proper spacing also makes pulling cables easier and reduces the risk of electrical interference or mechanical stress.
Port Plastics designs and manufactures duct bank and bore spacer cards from recycled high-density polyethylene (HDPE). Local production in Phoenix ensures short lead times and lower freight costs, while nationwide shipping keeps projects on schedule. Each spacer card is lightweight yet strong enough to support heavy conduit loads and can be customized to match your conduit pattern.
Why Choose Our Spacers?
Locally manufactured HDPE spacers
- Sustainable, recycled material: Our spacer cards are produced from re-processed HDPE. HDPE offers flexibility, strength and resiliency, giving the spacers enough “give” during the concrete pour to avoid kinking the duct walls. Double-wall construction allows them to support heavy vertical loads while remaining lightweight.
- Local production reduces delays: Manufacturing in Phoenix keeps business local and minimizes handling and freight costs. Short lead times mean your spacers arrive when you need them.
Faster, safer installations
- Quick assembly: HDPE duct spacers snap together from base and intermediate modules. Their interlocking design keeps tiers aligned and prevents movement during the concrete pour.
- Reduced labor time: Using spacer cards in the field drastically reduces installation time. Contractors can lay and align conduits quickly, helping projects stay on schedule and reducing man-hours.
Heavy-duty performance
- Support for large duct banks: The vertical and horizontal ribs of our spacers provide strength to withstand heavy loads and to maintain strong conduits. Each conduit is independently supported so that lower tiers do not deform under the weight of upper tiers.
- Resistant to weather and chemicals: HDPE spacers are durable and resist corrosion. They perform reliably in moisture, heat and cold, outlasting metal alternatives while requiring little maintenance.
Additional Materials and Services
- Arc-resistant FRP (red GP03) for electrical structures
- Acrylic/Polycarbonate for windows or viewports

Key Benefits of Duct Bank Spacers
- Maintain conduit spacing and level alignment
- Organize complex cabling
- Customization for project needs
- Cost-effective compared to metal alternatives
- Stackability for high-density systems
Applications
- Utility infrastructure: Electrical utilities use spacers to keep underground cables properly spaced and to reduce electromagnetic interference.
- Telecommunications and data centers: Organize and protect conduits in fiber-optic networks, 5G systems and data centers.
- Transportation: Highways, railways and airports rely on duct bank systems to protect cables under heavy loads.
- Renewable energy: Solar farms and wind turbines depend on weather-resistant spacers for underground cabling.

Frequently Asked Questions (FAQ)
What are duct bank spacers?
Duct bank spacers are modular plastic pieces that support underground conduits at regular intervals, keeping them level and preventing misalignment.
Why use HDPE spacers instead of metal spacers?
HDPE offers flexibility, strength and resiliency. It resists corrosion and extreme temperatures, is lighter, cost-effective, and easier to install.
How are duct bank spacers installed?
Base modules are placed in the trench, intermediate modules snap into place, and conduits are held securely during the concrete pour with interlocking mechanisms.
Where are Port Plastics duct bank spacers made?
Manufactured locally in Phoenix, Arizona with nationwide shipping available.
