Duct Bank Spacers and Underground Conduit Supports

Curbell Plastics supplies plastic materials and finished components for duct bank spacers, conduit spacers, conduit chairs, and custom underground pipe supports used in electrical, utility, telecom, and infrastructure applications. Our High-Density Polyethylene (HDPE) and PVC conduit support solutions provide impact strength and moisture resistance while helping maintain conduit separation, alignment, and elevation during trench installation and concrete encasement.

Large building and construction sites, such as hospitals, data centers and transportation networks, need plastic materials that are tough, durable, and can weather underground conditions. Plastic materials and machined parts for underground supports are cost-effective, allow for flexible designs, are easy to machine and provide broad chemical resistance.

Duct Bank Spacers for Electrical Conduit Installations

Duct bank spacers are used to support, separate, and align electrical conduits in underground duct bank installations. They help maintain consistent spacing between conduit runs during trench placement and concrete encasement, reducing movement and helping ensure the conduit layout stays properly positioned.

These spacers are commonly used in utility, telecom, commercial, industrial, and infrastructure projects where multiple conduits need to be organized below grade. HDPE Plastic and PVC duct bank spacers are lightweight, moisture resistant, non-corrosive, and easy to handle in the field, making them a practical choice for underground electrical conduit support applications.

Duct Bank Spacers, Bore Spacers, Conduit Spacers and Supports

Duct bank spacers and bore spacers offer utility and telecommunication providers the ability to easily and quickly install underground lines in channels and trenches for correct spacing underneath buildings, roads and transportation lines. The spacers help to support and maintain accurate duct position and alignment. Duct bank and conduit spacers not only support conduit bundles during installation but help to reduce load and stress, making installation and future installation or repairs faster and easier.

Curbell Plastics supplies HDPE sheets as well as machined HDPE duct spacers and bore spacers for construction applications. Spacers can be made from virgin HDPE or reprocessed HDPE material. HDPE does not absorb water and it does not corrode or rot. HDPE bore spacers are lightweight and they have soft surfaces that minimize damage to conduits during handling.

FRP Spacers, Pipe Shoes, Pipe Rollers and Other Plastic Applications

In addition, plastics can be used for other pipe support applications such as pipe shoes, pipe rollers and pipe chairs helping to minimize damage to pipes and piping systems.

C-TEK® Plastic Pipe Supports

These custom plastic pipe supports are extruded, then cut and drilled to customer specifications. C-TEK Plastic Pipe Supports are designed to separate the metal pipe from the metal support structure, they help prevent corrosion caused by metal-on-metal contact.

Their half-round shape minimizes water accumulation beneath the pipe, while the plastic material provides both thermal and electrical isolation, offering further protection in demanding environments.
