CP4 penstock
4-sided sealing

Due to the pre-tensioned seal, the CP4 penstock guarantees full sealing performance, even at low water pressure. Furthermore, it is suitable for unclean building openings, as the sealing surface to the wall is larger than the wall opening and thus leaks at wall breakouts are avoided.
