Tritube

Tritube is a high-density polyethylene extruded profile, stabilized in order to resist aging. It is comprised of three evenly sized round section tubes, positioned at the same horizontal level, and conjoined by a unifying sector. Its internal surface possesses longitudinal ribbing, capable of reducing attrition during the cable insertion phase.
Available in (40, 50) mm diameters
