ABSTRACT:
A window grating arrangement is placed across a window opening in a building wall to keep out burglars but can be removed from the window opening alongside the wall in a required time, especially so as to enable dwellers to flee in an emergency. The window grating arrangement is so constructed that a pair of parallel stationary supports are fixed on the surrounding portions of the window opening in the wall while a mobile assembly of protective bars are sustained slidably on the supports.
