What is a Horizontal cable? Think of it as a subway that connects your town to other towns. In actuality, it's a cable used on a Local Area Network (LAN) and it connects the network outlet to the patch panel from behind a wall.
WARNING: The plastic used in cable products can expose you to lead and lead compounds, chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
