Hubbell S1PT4X4AL Fire-Rated Poke-Through

Overview

The Hubbell SystemOne S1PT4X4AL is a one-piece, 4x4 aluminum fire-rated poke-through fitting designed for commercial installations. It provides a clean, code-compliant solution for routing power and communication cables through fire-rated floor and ceiling assemblies. This unit is engineered to maintain the integrity of the fire rating, preventing the spread of fire and smoke between building compartments. Its all-aluminum construction offers durability and corrosion resistance for long-term deployment in demanding environments. The S1PT4X4AL is suitable for new construction or retrofit applications where a single, integrated solution is required for both power and data cabling.

Compatibility

This poke-through fitting is designed to work with standard 4-inch square electrical boxes and compatible communication boxes. It is intended for use in fire-rated floor and ceiling assemblies where maintaining the assembly's UL rating is critical. Specific compatibility with building materials and fire-rated assembly designs should be verified against the relevant UL design documentation and local building codes. It supports the routing of up to four standard power cords and four communication cables (e.g., Cat5e, Cat6, fiber optic).

Installation Notes

Installation requires cutting a 4-inch diameter hole in the floor/ceiling assembly. The unit is secured using the integrated clamping mechanism, which engages with the underside of the fire-rated assembly. Ensure the supporting structure can bear the load. All power and communication cables must be routed and terminated according to NEC and local code requirements. The fitting is designed to accept standard 4-inch square electrical boxes and compatible communication boxes, which are typically mounted to the top flange of the poke-through.
