BULLET-PROOF LOCKDOWN SYSTEM
A lockdown barrier system and method includes a first mount that is secured to a wall surface and a sheet of shielding material formed of an anti-ballistic material that is moveable between a retracted position and an extended position. The sheet of shielding material has a first end that is secured to the first mount and a second end opposite the first end that is freely moveable away from the first mount. The system includes a second mount that is secured to the wall surface at a location that is spaced from the first mount. The second end of the sheet of shielding material is releasably connectable to the second mount and is secured proximate to the first mount when in the retracted position. The second end is secured to the second mount when in the extended position.
