The Lindy 40325 DP Port Blockers are a pack of 10 blue blockers for DisplayPort connections, used to close off ports that are not in use. The pack contains the blockers without a key.
Each blocker is a plastic cap that fits into a DisplayPort port and stays in place until removed with the dedicated key. By occupying an open port, it prevents cables, devices or foreign objects from being inserted.
The blockers also visibly mark inactive ports and are intended as a physical and visual deterrent against unauthorised access and port damage.
