A splice clip for coupling discrete sections of a wire mesh cable tray. The splice clip can include a bolt with a base, a first ledge, and a second ledge opposing the first ledge. The base and the first and second ledges can define a passageway along the bolt. The splice clip can also include a retainer with a set of pockets, including a first pocket and a second pocket, and a set of guidance features configured to translate within the passageway to guide the bolt along and in engagement with the retainer. The first pocket can be configured to receive a first wire of a first discrete cable tray section and the second pocket can be configured to receive a second wire of a second discrete cable tray section. The bolt can be movable along the retainer between an open position and a closed position.
