Each clamp includes an upright support having an adjustable edge wire retaining block thereon with a depending edge wire retainer. Further steps include selectively adjusting the edge wire retaining blocks on each clamp to a predetermined height with the corresponding edge wire retaininers longitudinally aligned and retainingly engaging the edge wire. And securing the respective blocks to the corresponding support for locating and stabilizing the row of springs adjacent the rail for maintaining the outer edge of the top coils of the row of springs adjacent the rail in a straight line and at a uniform height in order to facilitate the individual tying of the springs of the other rows of the springs together, and to the first row of springs and to the frame. And the edge wire clamp itself which further includes a manually operable grip for adjustably securing the support to the rail. A further grip adjustably secures the block to the support at a predetermined height.
