The security collapsible PRÆSIDIUM grate is the solution for protecting doors, windows and shop windows with maximum safety and functionality.
It can be opened completely, easily reduced into a pack on one or on both sides leaving the area totally free, and can be quickly closed for peace of mind and security by means of the patented sliding system and the special lock that locks the doors in three points.
In order to achieve resistance to cutting and breaking and entering, the profiles have been armour plated internally with revolving rods in galvanised steel. The horizontal levers are in carbon-nitrate steel (cut-resistant), galvanised and varnished in polyester powders making them corrosion- resistant (Certified). They are connected one to the other by metal bars, shaped and are stain-proof. The reduced depth allows installing the grate even in the presence of other types of frames, such as shutters.
Thanks the small pack, the grate can be fully retracted into a small box placed into the wall.
