In the OPTIMA/OPTIMAX system, Inner Corners 30 are used for forming rectangular corners (90°). In order to achieve an external corner, we use two formwork panels suitably combined with each other with outer corner clamp.
Standard dimensions of the Inner corners 30:
OPTIMA 30/60
OPTIMA 30/150
OPTIMA 30/270
OPTIMA 30/300
OPTIMAX 30/330
