Abstract: A device for maintaining a splicing bar in a substantially horizontally aligned plane in which said splicing bar supports a splicing tool and holder. The device comprises a mount for attaching the splicing bar to a vertical structure including attachment means for securing the mount to a variety of vertical structures by means of a standard keyhole slot engagement. The mount includes clamping means for fixedly securing said horizontally aligned splicing bar and stabilizing means for maintaining the mount in a substantially vertical plane. For use in certain applications, an adapter is employed which provides the necessary keyhole slots when not otherwise available.
