Manufactured by Hettich, a globally recognized leader in furniture hardware, this runner combines precision engineering, durability, and convenience, making it ideal for kitchens, wardrobes, office furniture, and modular cabinets. One of the key features of the KA 4532 runner is the Silent System mechanism, which ensures that drawers close softly and quietly without slamming. This damping system protects the furniture from wear and tear, reduces noise, and enhances user comfort, making it especially suitable for high-traffic areas such as kitchens, offices, and commercial spaces. The soft-closing action also minimizes the risk of injury, preventing fingers from getting caught in the drawer.
