Arnco releases flame-retardant fiber plenum
January 22, 2008 -- The Fiber-Guard Plenum is billed as a flame-retardant non-metallic flexible raceway for protecting optical fibers in accordance with NEC articles 770 and 800.
January 22, 2008 -- As a part of its flame-retardant conduit product line, Arnco Corp. has introduced its Fiber-Guard Plenum, billed as a flame-retardant and easy-to-install non-metallic flexible raceway for protecting optical fibers in accordance with NEC articles 770 and 800.
According to the company, the flexible and lightweight design of Fiber-Guard Plenum makes it easy to install and maneuver around obstacles that may be encountered in areas requiring plenum. The plenum's corrugated wall provides superior crush resistance for long-term protection.
The corrugated wall also reduces surface contact between the conduit's inside wall and cable jacket, helping to lower cable installation friction. The product is pre-installed with 1,000-pound tensile Bull-Line aramid pull tape to further help in reducing cable installation costs.
Available in either white or orange for easy identification, the Fiber-Guard Plenum has diameters of 1 inch, 1-1/4 inches, 1-1/2 inches or 2 inches to accommodate specific fiber cable diameters. Sequential footage marking and product identification are printed every two feet on the plenum, which has standard lengths ranging from 250-foot coils to 5,000-foot reels.
"Plenum-rated raceway provides superior protection, lowers installation costs and simplifies future building upgrades over traditional metallic conduit systems," comments Tom Stewart, director of conduit products at Arnco.
