Угловой профиль (или угловая планка)

The ALAKS Glazing Bead Corner Connector is a small plastic component used in traditional aluminum window systems to join glazing beads at the corners. Positioned inside the bead profile, it allows the four sides to connect precisely and securely, ensuring the glass remains firmly in place. Available in white and black, it matches common bead colors and, despite its compact size, plays an important role in maintaining the strength and integrity of the glazing frame.
