The corner fittings L 425 - 90° are used to connect roof membranes with rainwater drains close to walls and can be positioned either horizontally or vertically. The corner fittings are available in two sections to better suit water drainage requirements, and the flange is slightly inclined compared to the tang to facilitate the installation of the drain connector on a slope. The elasticity of the raw material with which they are produced allows for excellent flexibility even at low temperatures, enabling the mechanical and physical characteristics to remain unchanged for a long time. They have excellent resistance to deterioration caused by the sun, ozone and other atmospheric or chemical agents normally present. The completely smooth flange guarantees the perfect join with PVC synthetic felts, and the long 425 mm tang allows walls of up to 40 cm to be crossed. The drain connectors are perfectly compatible with prefabricated PVC synthetic sheets. Thorough cleaning of the drain connector and the synthetic felt is recommended near the connection area to the drain connector.
