The Unitrack system from Permobil combines a number of modular elements which together offer you a made- to-measure fit for optimal body support. Simply select the right support and the appropriate adjustable joint and fit them where required. The system is infinitely adaptable and adjustable. Only a half-turn of the rapid release handle is needed to remove the support. There are no protrusions on the handle so it will not catch on anything. The Unitrack system is exclusively designed for the Corpus seating system.
