Metal cable glands are mechanical devices that are used to secure and seal the ends of electrical cables that are passed through metal enclosures or panels. Cable glands are used to provide a reliable connection and to prevent dust, dirt, moisture, and other contaminants from entering the enclosure or panel.Metal cable glands are typically made from materials such as brass, aluminum, or stainless steel, and are designed to provide a secure and durable connection. They come in different sizes to accommodate different cable diameters and are available in a variety of configurations, such as straight, 90-degree, or 45-degree angles.
