A cable barrier system including a cable-release anchor assembly, a terminal end section having at least one terminal post, the terminal post disposed adjacent to and spaced from the cable-release anchor assembly, and a length of need section having a plurality of line posts spaced from each other, each line post having an internal cavity and a slot formed along a sidewall extending downward from its top end. At least one cable having a terminal end is connected intention between the cable-release anchor assembly and the posts, the cable connected to the cable-release anchor proximate its terminal end. The cable is releasably connected to the terminal post and the line posts. The cable is releasably connected to the line posts by post-cable connectors. The post-cable connector includes an elongated section forming loops, the elongated portion is disposed substantially within the cavity and the loops extend through the slot to the exterior of the cavity. The cable is slidably disposed in the loop. Wherein when an object impacts and deforms one of the posts toward ground level the cable is released from the deformed post in a manner such that the cable tends to stay in contact with the object.
