Legrand Floor Boxes are Fire Rated for up to Three HoursEngineering
WEST HARTFORD, Conn., (July 23, 2014) – Legrand now offers 19 Wiremold® flush style floor boxes that have been evaluated, tested, and approved to meet UL Fire Classification requirements for at minimum a two-hour floor rating and, in many cases, a three-hour rating. Available in both single and multiple-gang versions in steel and nonmetallic fabrications, they provide power, communication, and audio/video services into open spaces. These boxes also accept existing cover plates and service fittings to present a more consistent and aesthetic finish throughout the building.
The Evolution™ Series Floor Box has a three-hour rating. Boxes are available in 6-, 8- and 10-gang configurations. Its unique design allows the boxes to be installed in carpet, tile, and wood-covered concrete; terrazzo; and polished concrete floors without additional parts or accessories for above-grade fire-classified applications.
The family of Wiremold UL listed and fire-classified floor boxes includes:
- One-, two- and three-gang OmniBox™ steel floor boxes
- Resource RFB® two-gang and four-gang multi-service steel recessed floor boxes
- 880MP and 881 Ratchet-Pro® nonmetallic floor boxes
- Evolution Series steel floor boxes
When properly installed, fire-classified floor boxes save time and money for general contractors and installers by eliminating the need for spraying or using other solutions to meet the building requirements. They also eliminate the guesswork for inspectors and provide reassurance for building owners and property managers by meeting or exceeding the UL Fire Classification Standards.
