The Internal Curve is used to alter the edging direction by 90 degrees in the opposite direction to the external curve. The 'Internal' in internal curve relates to the fact that the mower strip is on the inside of the curve as opposed to an external curve where the mower strip is on the 'outside'.

When used in conjunction with the other components it is possible to create many designs. An example is the photo on the right which shows a wave pattern.

Each internal Curve is supplied with 1 stake.
