An apparatus, called a wedge deadend, used to secure aerial fiber optic transmission lines or cables. The deadend and secured cable can effectively be attached to support structures such as poles or towers. The wedge deadend has a single assembled frame with an attaching cable for mounting to the support structure and two wedges that slide into the frame. The frame consists of two parallel plates. Each plate has two slots that are tapered and angled toward one another. The wedges are similarly tapered enabling them to be interlocked with the side plates. Both wedges also have a groove that is sized and textured to grip a specified cable. The wedges can be designed to compress the encased cable evenly along the entire contact surface of the wedge, or with varying force along such surface.

Wedge deadend to support aerial cables

A straight line, side opening dead end cable clamp includes a pivotally mounted keeper that is spring loaded on the cable clamp body to urge the keeper into an open position. The body of the clamp has a very low profile permitting it to be formed in a mold that has a straight parting line. A cable receiving groove is formed in the body at an angle to bring the axis of the cable in line with the supporting clevis. The keeper has an elongated cable compression member that is maintained in alignment with the cable receiving groove. A single and a double U bolt design are disclosed. The compressive force applied to the cable by the cable compression member and the cable supported groove in the body is maximum at the supportive end of the clamp and minimum at the mouth of the clamp. A double loop spring member couples the keeper to the body and urges the keeper to an open position to permit access to the cable receiving groove.
