Duct Spacer
Gamson manufactures high-durability Duct Spacers (also known as conduit spacers or underground markers), designed to provide organized and stable support for multiple duct banks in underground utility installations. These spacers ensure precise horizontal and vertical separation between HDPE pipes, which is critical for preventing heat buildup in electrical lines and maintaining structural integrity during concrete encasement or soil backfilling.
Key Features
- Consistent Alignment: Maintains exact spacing between ducts, ensuring that the entire utility run remains straight and organized according to engineering specifications.
- Snap-Lock Design: Features a user-friendly interlocking mechanism that allows spacers to be quickly connected side-by-side or stacked vertically without the need for specialized tools.
- Enhanced Load Distribution: Engineered with a wide base and high-strength ribs to support the weight of the ducts and the pressure of the backfill, preventing pipe deformation.
- Superior Flow for Encasement: Designed with large open spaces to allow for the free flow of concrete or grout during concrete encasement, eliminating voids and air pockets.
- Chemical & Corrosion Resistance: Molded from heavy-duty, non-conductive plastic that is immune to soil acids, moisture, and electrolytic corrosion.
- Reduced Installation Time: The modular design allows for rapid assembly on-site, significantly reducing labor costs compared to manual spacing methods.
