Manufactured from High Density Polyethylene (HDPE), Smoothwall is intended for use in underground, aerial, and innerduct applications. Smoothwall offers superior protection, increases pathways of existing duct systems and allows extra channels for future cabling needs. Cable can be installed by pre-installed pull-rope or jetting. Standard colors include black or orange; custom colors and striping available. Sequential marked footage is standard. Options include internal ribs, silicone pre-lube, aerial UV protection, pre-installed pulling tapes, and multiple reel configurations (source: distributor product pages).
