CableDuct PL is a UL listed, small diameter (1", 1-1/4", 1-1/2", 2" ID) raceway produced from PVDF that meets or exceeds all Underwriter Laboratories requirements for installation in plenum areas.
Please note: While CableDuct PL is UL approved for use in plenum spaces, plenum cable is still needed; the use of CableDuct PL does not eliminate the need for plenum cables in plenum environments.
CableDuct PL provides a clean, low-friction path for the installation of optical fiber cables. In areas that are hard to access, this highly flexible raceway can be installed first; the cable can then be pulled through the raceway in one continuous length. CableDuct PL also serves to isolate, protect, and identify critical optical fiber cables in plenum areas. Although it has low-friction qualities, cable lubricants are recommended when pulling cable through the raceway. CableDuct PL is designed for the installation of one cable per raceway; installation of multiple cables is possible, but multiple cables in a raceway will cause higher friction, resulting in shortened cable pulls. A fill factor of cable OD to raceway ID of 50% is the maximum recommended.
CableDuct PL is very flexible; extra care must be taken to eliminate all bends and snaking during installation to lessen excessive friction (resulting in relatively shorter cable pulls); the raceway must be tied down to prevent movement during the cable pull. The suggested method is tie wraps placed every two feet and at the beginning, middle, and end of each bend or offset. Ninety degree bends or sweeps must have a minimum radius of three feet.
Plenum (for more information on CableDuct PL, click here) A raceway marked "Plenum" is suitable for use in ducts, plenums or other spaces used for environmental air when used to enclose optical fiber cables marked OFNP or communications cable marked CMP or CMP-OF. This raceway exhibits a maximum peak optical density of 0.5, a maximum average optical density of 0.15, and a maximum flame spread distance of 5 feet when tested in accordance with the Test for Flame Propagation and Smoke-Density Values (Plenum) in UL 2024. A marking on the surface of the raceway or on a marker tape indicating "Plenum" identifies this raceway.
Riser (click here for more information on CableDuct RI )
A raceway marked "Riser" is suitable for installation in risers when used to enclose optical fiber cable marked OFNP and OFNR or communications cable marked CMP, CMP-OF, CMR or CMR-OF. This raceway has fire resistant characteristics capable of preventing the carrying of fire from floor to floor. This raceway exhibits flame-propagation height of less than 12 feet and a temperature of less than 850 deg. F. at the 12 foot point when tested in accordance with the Test for Flame Propagation (Riser) in UL 2024. A marking on the surface of the raceway or on a marker tape indicating "Riser" identifies this raceway.
