Hubbell S1R4SPTWIST Fire Rated Poke Throughs Recessed 4in. Sub Plate

Overview

The Hubbell S1R4SPTWIST is a recessed 4-inch sub-plate designed for fire-rated poke-through applications. It provides a clean, code-compliant method for passing cables through floors while maintaining the integrity of fire barriers. This component is essential for installations requiring adherence to building codes and fire safety standards, ensuring that cable penetrations do not compromise the fire-resistance rating of the floor assembly. Its design facilitates a professional finish in commercial and industrial environments.

Compatibility

This sub-plate is specifically engineered for use with Hubbell fire-rated poke-through systems. It is designed to integrate with systems that require a 1.60-inch opening for cable passage. Consult the Hubbell poke-through system documentation for exact compatibility with specific floor types and fire ratings.

Installation Notes

Installation requires adherence to the specific poke-through system's instructions. Ensure the 1.60-inch opening is properly prepared and that the sub-plate is securely fastened to maintain the fire rating. Proper torque and sealing are critical to prevent smoke and fire migration. Tools required typically include standard hand tools for mounting and potentially a sealant gun if specified by the poke-through system.
