Ribbed In/Ribbed Out In HDPE is a high-performance conduit used for underground installations into main conduits. Ribbed In/Ribbed Out In HDPE provides for reduced surface contact between inside walls and the cable resulting in reduced friction and easier cable placement. Additionally, the outer ribs reduce the twisting and friction when installing into a main conduit. Ribbed In/Ribbed Out In HDPE is packaged in continuous lengths on reels or coils allowing for fast installation with minimum joints. Ribbed In/Ribbed Out In HDPE is available in numerous colors and stipe combinations for easy identification.
Bull-Line pull tape can be pre-installed in Ribbed In/Ribbed Out In HDPE. This eliminates the need to install a measuring or pull tape after installation.
Dura-Line Inside and Outside Ribbed HDPE Conduit is made to Industry Standards for Power and Communications Applications. It can be installed using open trench methods, HDD (Horizontal Directional Drilled) Plowed, or pulled into conduit.
With optional SilicoreTM Permanently Lubricated Lining, Ribbed duct can be maximized for greater pulling and jetting distances, reducing the coefficient of friction over standard HDPE conduit. When pulling into an external conduit, the outside ribs reduce wall to wall contact which reduces pulling stresses, maximizing distances that can be placed. Dura-Line Inside and Outside Ribbed conduit is available up to 2” diameters.
