CT120 Pass Through Devices / Cable Transits

Abesco CT120 Cable Transits are firestop devices which are designed to allow cables to penetrate fire-rated floors and walls. They consist of a square section steel sleeve, which contains the heat reactive graphite based intumescent material. The transits can be opened to provide an easy retro-fit option where cables are pre- installed, and are designed to allow for the installation or removal of additional cables. When exposed to temperatures of approximately 300oF the graphite based intumescent material begins to expand (intumesce) rapidly to form a solid insulating char plug which effectively closes and seals the CT120 to prevent the passage of fire and smoke thru the fire-rated wall or floor.

Each year many thousands of deaths, injuries and an immeasurable amount of property damage occur as a result of fires. Containing a fire at it’s source using passive fire protection can significantly reduce the rate in which a fire spreads throughout a building. High quality products installed properly can perform as intended and gain that vital additional time which could mean the difference between relatively minor damage and total loss.  Make sure your cables are properly firestopped with an Abesco Pass Through Device!

 

Abesco CT120 Cable Transits (Fireclamp) are a one-piece hinged metal firestop device designed for quick installation into fire-rated floors and walls.The square or round devices form a steel sleeve, which contains the heat reactive graphite based intumescent material with foam smoke seals and optional mounting brackets.

The transits can be easily opened to provide an easy retro-fit option or new construction where a permanent firestop application is needed.  Cables are installed and removed quite often at some facilities, make sure your option has the certification needed to perform.  Our devices have 0 to 100% cable fill options!

Suitable for use in concrete walls and floors, gypsum walls, wooden floors, and drywall

  • Tested to EN1366-3, BS476-20, ASTM E-814 (UL1479) and AS1530-4
  • Designed for single or multiple cables
  • Easy to install before and after cabling
  • Easy installation-saves labor cost
  • Approved worldwide and recognized by independent authorities

How the CT120 works:

Cable Transits (CT) are used to seal cables which penetrate through up to 4 hour fire-rated concrete walls and floors, and are suitable for most common types of construction.

Individual CT120 Cable Transits can be ganged together to form duplex, triplex, or sixplex units using special CT Mounting Flanges(which are listed below).

CT systems are suitable for data, communications and electrical supply cables, and even pipes; CT120 Cable Transits offer flexibility, expandability, and reliability from 0-100% fill

Leakage Ratings:

The CT 120 Devices have unparalleled leakage ratings, the best in the industry. They can be rated from blank to 100% filled and don’t require putty to do so. Leakage ratings of less than 1 cfm are common!
