The APC Electronic LY-SB01B is a single-port surface mount box designed for RJ45 network connections. This housing provides a clean way to install a network outlet on a wall or surface without needing to run cables inside the wall, making it a practical choice for adding a network point to an existing room. It features one port for an RJ45 connection, though the keystone jack is not included and must be added separately to match your specific cabling needs.
