Yale Blade espags feature a unique blade or wave locking mechanism that engages the full length of the keep. Designed to sit flush within the Eurogroove, this system allows for separate installation of the keep and lock prior to hanging the sash, delivering greater flexibility and efficiency during fabrication. The unique rotating action of the lock provides users with a smooth and easy-to-close window, minimizing wear on components and ensuring a long service life with no loss of compression.
