Abstract
A chain link fence slat system comprising a plurality of slats and a channel. Each slat is elongated and has a longitudinal dimension with a first and a second end, a width dimension and a thickness dimension less than the width dimension. Each slat further has at least a first and a second notch formed near the first end of the slat, each of the notches being formed on opposite sides of the width dimension and extending across the width dimension and partly through the thickness dimension. The first notch is positioned at a first vertical height and the second notch is positioned at a second vertical height with the second vertical height being greater than the first vertical height. The channel receives one end of each slat. The channel has inner surfaces including a base portion, a first opposing wall and a second opposing wall. The first opposing wall has a first inwardly projecting barb for receiving the first notch of a slat and the second opposing wall has a second inwardly projecting barb for receiving the second notch of a slat. The spacing between the first and second opposing walls being equal to or greater than the thickness dimension of the slat.
