3" CS-3 Plastic Wall Sleeve - Century-Line

Century-Line wall sleeves are made of polyethylene. That makes very strong and only 1/8th the weight of similar steel sleeves! This means easy installation - even by one person. HDPE is resistant to a wide range of acids and solvents. Install by placing the sleeve where pipe will go before pouring the wall/barrier. For a complete water-tight system use with Link-Seal modular seals. Model: CS-3, Material: HDPE, ID (in.): 2.94, ID (mm.): 74.7, lbs: 1.3, Kg: .59
