A waterproof cable gland (also known as a cord grip) is a device used to aid in the connection of cables or wires within an electrical or electronic enclosure. The cable gland helps to maintain the watertight seal where the cable or wire enters the enclosure. Consisting of a body and a nut, the glands could either contain a separate gasket and cable seal or these components could be integrated into the body of the gland. Poly case offers both varieties. The cable gland is then assembled within a circular cutout in the enclosure, capturing the wall of the enclosure between the body and nut creating that watertight seal.
