Universal slotted and unslotted waste fittings are versatile drainage components designed for use with basins, sinks, or washbasins, whether they have overflows or not. Slotted wastes are equipped with a slot that allows excess water to drain away efficiently, preventing overflows, while unslotted wastes are suitable for basins without overflows, providing a secure seal to prevent leaks. These fittings are compatible with a variety of basin designs, ensuring proper drainage and maintaining hygiene and functionality in bathrooms or wash areas.
