| Endocor 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. While Endocor PL is UL approved
for use in plenum spaces, plenum cable is still needed; the use of ENDOCOR
PL does not eliminate the need for plenum cables in plenum environments.
Endocor 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. Endocor
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. Endocor
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.
Endocor 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.
Endocor PL can be supplied with an
optional kevlar tape to pull cable into the raceway.
