The new FlameStopper thru-wall/floor fittings from Wiremold / Legrand have been redesigned to provide firestopping solutions for both new and retrofit applications. Flamestopper Thru-Wall/Floor Fittings provide installers with a variety of UL Classified ready-to-use options for transitioning cables through firewalls and floors to ensure that the integrity of the fire rating is maintained. These fittings have been tested by Underwriters Laboratories Inc. to ASTM E814 UL1479, Fire Tests of Through-Penetration Firestops. The Flamestopper Thru-Wall/Floor Fittings offer a passive fire and life safety system with ratings up to four hours (with or without cables installed) to complement existing sprinkler systems and up to three hours for through floor applications.
