Roto FTT has developed a flexible corner drive for designer pivot and tilt-turn aluminum windows. The company first presented the product at the BAU exhibition in 2023. Now, the Roto Object division of the Roto Aluvision branch has introduced an accelerated testing process for clients who want to install custom-shaped windows.
The flexible corner drive is intended for inward and outward opening windows with obtuse and acute angles. It is compatible with Roto AL and Roto AL Designo hardware for concealed installation.

According to Roto, any number of locking points can be placed along the entire outer side. Therefore, a trapezoidal window can achieve the same sealing properties and RC2 burglary resistance class as a conventional rectangular standard window.
The corner drive is fixed with four screws.
