The one-part connecting rod of the new Roto NX Plus lever-operated espagnolette causes a connecting-rod movement that is synchronous with the lever. The advantage: the uniform position of the strikers in the active and passive sash and the use of just one jig for both sashes facilitate installation and prevent confusion.
The lever of the new Roto NX Plus lever-operated espagnolette is almost at 180° in the opening position. The espagnolette is delivered in this exact turned position, i.e. the open position, so the fixing screw is immediately accessible. The espagnolette is quickly cropped, the sash quickly installed.
