Ribbed In/Out

Manufactured from flexible HDPE, makes gradual bends
External ribs help reduce spiraling during duct installation and reduces installation forces when installed into conduit
Internal ribs reduce the the coefficient of friction
Continuous lengths reduce joining costs
Excellent low-temperature properties
Outstanding long-term cable protection

CoExtruded

The co-extruded color layer provides a full exterior appearance
Color layer is made from same HDPE as inner wall – performance properties are unaffected
Total wall thickness = inner black thickness + external layer thickness
Color fastness and UV protection performance for co-extruded conduit is equal to full wall colors
