The movable frames are systems that allow elements of the 19" to be simultaneously located in a simple and practical form, since they allow the access to the back of the equipment simply by turning the device. They are made of 1,5 mm. thick sheet metal. Painted in a grey textured RAL 7035. The frame allows maximum depth of the assembly thanks to the location, lateral and central, when necessary. This system is made in the cabinets 800x600 and 800x800 under request.
