Overview

The ABB SP4W15-1 4-inch One-Way Snap-N-Stac Non-Metallic Combo Spacer is engineered for efficient, corrosion-resistant cable and conduit management in concrete-encased duct bank installations. Manufactured from high-impact polystyrene (HIPS), this spacer combines the functionality of a base and intermediate spacer into a single, robust unit, eliminating the need for separate components and reducing inventory requirements. Key specifications include a 1.5-inch duct-to-duct spacing for optimal cable separation, ensuring proper airflow and thermal management in high-density installations. The non-metallic construction provides superior resistance to corrosion, moisture, and electrical conductivity, making it ideal for harsh industrial and commercial environments. The exclusive horizontal and vertical locking system allows spacers to interlock securely, regardless of size, enabling stable, long-term alignment during concrete pouring. Designed for versatility, the SP4W15-1 accepts 4-inch duct sizes and can be installed horizontally, vertically, or upright to accommodate unique duct bank configurations. The one-way design simplifies installation in linear runs, while the molded-in rebar holder (available on two-way and three-way models) enhances structural integrity when required. Compatible with ABB’s Snap-Loc reducers, the SP4W15-1 can also accommodate smaller 1-inch or 2-inch conduits, providing flexibility for mixed-size duct systems. Installation is streamlined with the Snap-N-Stac system: spacers slide together via male-female adapters, and odd-numbered duct runs can be configured by cutting two-way spacers into one-way units. The thermoplastic material ensures durability under concrete pressure, withstanding the rigors of construction while maintaining dimensional stability. Trust ABB’s SP4W15-1 for reliable, code-compliant cable management in underground, concrete-encased applications where performance and longevity are critical.
