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!
Packaging
- Abesco CT120 Cable Transit devices are individually boxed and labelled but sold in shipping cases of 6 devices.
- Abesco CT Mounting Flange Sets and CT Stud Mounting Brackets are packed and labelled individually in clear sealed bags before being packed into their shipping cases.
- Abesco CT Mounting Flange Sets include brackets for both sides of walls or floors. Ask about how our CT120 Cable Transits can be top side only mounted in floors.
