Base Duct Spacers | Interlocking Design | High-Impact Polymer
Base Duct Spacers provide durable, precision alignment for underground duct installations. Engineered for both encased and direct burial applications, these high-performance spacers simplify duct bank assembly while ensuring long-term system stability under heavy loads.
Key Features
- Innovative Interlocking System – Vertical and horizontal interlocks enable fast, secure assembly while maintaining perfect duct alignment and spacing in the field.
- High-Impact Durability – Constructed from heavy-duty polymer for superior strength and load support without deformation or cracking under pressure.
- Versatile Application – Designed for encased or direct burial installations, compatible with multiple duct sizes and materials.
- Easy Field Installation – Lightweight design allows for quick setup and precise stacking—ideal for both large-scale infrastructure and small utility projects.
