A draw latch is a mechanical fastening device commonly used to secure doors, lids, or panels. It consists of a hook and a catch, allowing for easy opening and closing. When the hook is pulled down, it engages with the catch, creating a tight seal that keeps the object closed. These latches are often made from materials like stainless steel or zinc-plated steel, providing durability and resistance to corrosion. They are widely used in various applications, including cabinets, toolboxes, and storage containers, making them a practical choice for both industrial and residential settings.
