The Kisner KADS Parapet Clamp Ring Drain is a robust, high-performance drainage solution for flat roofing and façade systems requiring lateral discharge through parapet walls. Available in 3” (62–75 mm) and 4” (90–110 mm) outlet sizes, it ensures a watertight, long-lasting connection to existing pipework across a range of waterproofing systems.
The Kisner KADS Parapet Clamp Ring Drain is engineered to provide reliable horizontal drainage through parapet walls, ensuring secure, leak-free water discharge from flat roofs. Each unit features a precision-moulded rubber gasket that guarantees a highly sealed connection with standard pipework, preventing leaks and backflow even under varying pressures.
Constructed from durable polypropylene (PP), the drain body offers outstanding resistance to UV radiation, frost, and temperature fluctuations. This model supports installation with no membrane, butylene fleece, or EPDM, providing complete flexibility across different waterproofing systems.
Designed for both new construction and refurbishment projects, it delivers dependable performance and a clean, professional finish to parapet drainage details.
