Select the width you wish to use and place the Kast-Spreader into the split cast until the 8 appendages are flush with the cast surfaces.
Place as many Kast-Spreaders along the split cast as necessary. After all the Kast-Spreadedrs are in place, release the cast stretcher so that the Kast-Speader will be held in place by the cast. By design, the cast spilter will not penetrate the cast or touch the skin.
If necessary for casts used in vigorous movement, after spreading the cast, secure Kast-Spreader with a strip of medical tape.
The Kast-Speader can be used vertically or horizontally depending your needs for a cast spreader.
