If you're installing or upgrading cabinets and want that smooth, high-end feel, these GRASS Hetal Kinvaro flap fittings are absolutely professional grade! Designed for flap weights between 3.8 to 19.2 kg, these German-engineered hinges provide incredibly smooth operation with integrated closing damping that prevents slamming. The opening support feature holds flaps securely in any position, which is so convenient when you need both hands free while working in cabinets. The 3-dimensional adjustment system (±1.5mm in height, side, and tilt) makes installation and fine-tuning much easier, ensuring perfect alignment even if your cabinet isn't perfectly square. The pre-assembled Euro screws and positioning pins streamline installation, and the tool-free clip front mounting means you can remove and replace flaps without any tools. The package includes everything you need - left and right fittings, mounting brackets, cover caps, connecting hinges, and a drilling template for precise installation. These are specifically designed for flaps with widths between 400-1200mm and heights from 520-900mm, so make sure to measure your cabinets before ordering. Whether you're a professional cabinet installer or a serious DIYer wanting premium results, these GRASS hinges deliver that luxurious, soft-close action that makes even basic cabinets feel high-end and professional.
