STI's EZ-Path® Series 33 Fire-Rated Pathway Device Kit w/ 4-Gang Plate is designed for installations requiring multiple cable pathways within a single organized wall opening. The 4-gang configuration accommodates four Series 33 pathways in a nominal 3 in. x 9 in. wall opening, making it well suited for telecommunications rooms, data centers, commercial buildings, and other structured cabling applications. Its self-sealing design helps maintain fire and smoke resistance as cables are installed, removed, or replaced, reducing the need for repeated firestop material application during system changes. The Series 33 pathway is tested to ASTM E814 and CAN/ULC-S115 standards and is designed for fire-resistance applications when installed according to the manufacturer's tested system requirements.
