PortSavers protect the wear and tear of computer ports! Notebook computer ports are impossible to repair if worn out as a result of constant plugging and unplugging of cables and peripherals. A PortSaver is inexpensive and can be easily discarded and replaced. This slim adaptor attaches securely and works with any DB9 connections including RS232 serial, monochrome and multisync monitor ports. (Connectors: DB9 Male to Female)
