A cable release for use in a curtain control system for controlling drop curtains in a livestock confinement building. The cable release operates with cable drop devices having a cord release. A U-shaped segment of a main cable attached to the drop curtains is held in tension by an anchor with a latch operated by a lock handle attached to the cord of the cable drop device. The curtains are dropped when the cord is released by the cable drop device and U-shaped segment is released from anchor.
