Abstract
Abstract A high security grating which resembles a conventional wooden window shutter. The shutter uses crossbars which extend across a door or window into a shutter frame. A tie rod extends through bores in the crossbar ends to tie the crossbars together and hold them in place. A metal frame covers the tie rods and shutter blades cover the crossbars. The shutter blades can be pivoted using an operator rod. The shutters are mounted inside a building using heavy duty hinges and deadbolts which allow them to be alternatively closed over a door or window or folded away to the side.
