A mid-span clamp includes an elongate base that defines a cable channel on a top side. The clamp includes a first pressure block connected to the base by a first control arm. The first pressure block includes a clamping surface and a top surface. The top surface includes a cleat. The clamp includes a second pressure block connected to the base by a second control arm. The second pressure block also includes a clamping surface and a top surface. The top surface includes a cleat. The clamp has an open position and a closed position. In the open position, a cable passageway is defined between the clamping surfaces of the first and second pressure blocks and the cable channel of the base. In the closed position, the clamping surfaces of the first and second pressure blocks close the cable passageway. The clamp is biased in the closed position.
