The “Central Spine Systems”, that are those systems provided with a central element to whom the desks are connected perpendicularly, are here represented by the program Vertebra (spine) with Pigreco (desk).“Vertebra” double-sided for opposed workstations. On top of the “Vertebra” it has been fixed a screen panel of 30 mm thickness equipped with accessory rails for stationery and monitor arms that, other than improving the functionality, segregates the workspace and create privacy.Vertebra can be single sided ora double sided, fully wireable as Cables run along the skirting and exit through the grommet.The most evident advantage that this work solution offers consists in the possibility of obtaining a high level of privacy and a very comfortable access to filing and use the skirting of the central spine to wire manage the cluster without necessarily using raised floors.
