These metal plugs provide durability and help prevent interference with the signal. They have a threaded design that allows for a secure and stable connection to the Co-Axial cable, reducing the risk of disconnection or signal loss. They can be easily installed by screwing them onto the Co-Axial cable end and then plugging them into the desired device. They are commonly used to connect devices such as televisions, cable modems, or routers to Co-Axial cables.
