Retractable security barrier
A retractable, coilable, security barrier screen easily mounted around a door, window or other building opening such as a hallway entrance. The barrier is designed to withstand considerable forces from blunt force strikes, bullets and edged weapon slashing. As such, it has a strengthened spool tube, novel security barrier attachment methods, and redundant operational features such as dual (top and bottom spool locks), quad spool locking pins and a dual attachment for the fabric security barrier to the screen lock strip that includes both gluing and plate riveting.
