Technical Information
P&C Flex
®
conduit is flexible. Carlon

P&C
Flex
®
Non-Metallic Corrugated Conduit is used
to transition from Carlon
®
P&C Duct Type DB.
Despite equipment being mounted away from
the pole, P&C Flex
®
conduit remains flush to
the pole.

Guard
When soil conditions do not permit
direct burial of cable, use Carlon

P&C
Flex
®
Non-Metallic Corrugated Conduit
to protect the cable. A lower coefficient
of friction provides easy wire pulls on
location. Flexibility eliminates the need
for elbows.
