Ringed protective sleeves with color stripes
Our color-banded protective sleeves (also known as Janolene) provide extra protection for buried pipes and ducts against impact and crushing.
Ringed sheaths and protective sleeves
TPC sheaths and corrugated sleeves (also known as Janolene) feature a double-wall construction: a smooth inner surface (for easy cable or pipe pulling) and a corrugated outer profile (for rigidity and mechanical strength). TPC's coefficient of friction improves cable pulling.
