CT120 Cable Transit Firestop System – Penetration Sealing Device Kit

The Abesco CT120 Transit device is designed for use across multiple construction types, including gypsum drywall assemblies, concrete walls and floors, and wooden flooring. It is used to seal cable and service penetrations in fire-rated structures.

CT120 Cable Transits are used to seal cables passing through fire-rated concrete walls and floors with ratings of up to 4 hours. These systems are suitable for data, communications, and electrical supply cables, as well as pipe penetrations, providing flexibility and expandability from 0% to 100% fill. Individual transits can be combined into duplex, triplex, or sixplex configurations using compatible CT mounting flanges.

The CT120 device offers low leakage performance, with ratings typically below 1 cfm across fill conditions from empty to fully filled, without requiring additional putty, supporting consistent sealing performance in firestop applications.
