Window Opening Restrictor

This is a type of friction brake mounted between the window frame and sash, typically preventing the sash from opening beyond a 90° angle. It protects the window from hitting the frame due to strong winds or drafts. An additional advantage of this solution is its ability to hold the window in the position selected by the user.
