Aquabocci Blade R-47 is a level threshold drainage system for the space between the living area and balcony. The open side entry point features an EPDM silicone sleeve that sits below the door track to carry the water into the drainage channel. At the same time surface water is drained through the top entry point providing complete drainage in the most minimal way possible. The system is available in four anodised colours and therefore easily matches the respective bifold or sliding door.
