Scrigno Belvedere can contain an external sliding concealed element, like a shutter or a grating, combined with an internal swing casing. The sliding system for the external element is designed to require only minimum force for opening and closing and thanks to this system it is no longer necessary to lean out to open or close external shutters. It is ideal for use on the ground floor as shutters can be opened without creating a hazard for people passing by. The grating offers additional security and can be used only when required. The frame has strong anchorage points for a lock. It has a counter-frame for the internal swing casing. Available in single and double versions, in sizes varying to the nearest centimetre.
