Corner fittings L 425-45° are used to connect roof membranes with rainwater drains placed near walls and can be positioned either horizontally or vertically. The special 45° shape of the flange is suitable for screeds with a chamfer instead of the 90° angle. 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 elastic material from which they are made guarantees a watertight seal over time. They have excellent resistance to deterioration caused by the sun, ozone and other atmospheric or chemical agents normally present. The wide, completely smooth flange guarantees the perfect join with PVC synthetic felts, and the long 425 mm tang allows them to pass through walls of up to 40 cm. The drain connectors are fully compatible with prefabricated PVC synthetic felts. Thorough cleaning of the drain connector and the synthetic felt is recommended near the connection area to the drain connector.
