Abstract: A roll-by spacer and trolley system for use with a wire and method thereof is provided. The system includes a trolley having at least one rotatable wheel. The rotatable wheel has a first wire contact surface positioned to contact and roll along the wire. A spacer is suspended from the trolley with a connecting element between the trolley and the spacer. The connecting element has a first position wherein the trolley and spacer are connected and a second position wherein the trolley and spacer are disconnected. A wire engagement structure is connected to the spacer. The wire engagement structure has a second wire contact surface that contacts the wire when the connecting element is in the second position. The second wire contact surface is positioned above first wire contact surface when the connecting element is in the first position.

Abstract: An angle block apparatus and method of stringing cable is provided. The apparatus includes an angle block frame having an enclosed frame perimeter structure. A rotatable roller wheel is connected to the angle block frame and positioned interior of the enclosed frame perimeter structure. A connector is affixed to the angle block frame and sized to retain the angle block frame in a substantially stationary position. The method of stringing cable includes, in part, disconnecting a sled carrying the cable from a messenger wire trolley. The sled and cable attached thereto is then moved through the angle block frame from a first side to a second side of the angle block frame. The trolley is moved from the first side to the second side of the angle block frame without going through the angle block frame. The sled is then reattached to the messenger wire trolley on the second side.

Abstract: A stringing messenger clamp for use in overhead transmission and distribution systems and method of installing a messenger cable is provided. The stringing messenger clamp includes a bracket and an assembly body supported by the bracket, wherein the assembly body has a cable channel sized to receive a portion of a messenger cable. An assembly clamp is movable with respect to the assembly body and closable upon the cable channel. When the assembly clamp is in a closed position, it retains in place the portion of the messenger cable within the cable channel.
