The Hubbell S1DIV1 is a gray composite side-by-side divider designed for use with Hubbell SystemOne floor boxes, including models such as S1PFB, S1SFB, and S1CFB. This durable replacement divider mounts directly onto the sub-plate to create separate compartments, allowing for organized power, data, voice, and A/V wiring within a single floor box. Constructed from high-quality, UL 514 and cULus-certified materials, it ensures safe, reliable performance in both flush and fire-rated poke-through applications. Measuring approximately 5.6″ W × 5.7″ L × 2.3″ H, the S1DIV1 offers a compact and efficient solution for maintaining clean, code-compliant floor box installations.
