End profile for plasterboards for convex and concave curves. In addition, the plasterboard's plaster core is protected. The perforated leg must be filled over the entire surface towards the centre of the board in order to achieve a flat transition between the profile and the plasterboard. The end profile is made of PVC and has a removal edge and round hole punching on one side. For shaping arches, a leg with punched-out holes (slots) is attached.
