The adjustable skates each consist of a pair of skates which can be connected using two steel rods. The rods are loose inside tubes welded onto the edges of the skates. The distance between the skates can be freely adjusted from 500 to 1400mm (model CM60) or 720 to 1500mm (models CM120 and CM240). The rods prevent the skates from skidding and travelling at different speeds. This is especially important when turning.
