The combination of Concealed Hinge (BO) and Hidden Door Closer (CO) form the so-called CO-BO System. Hidden hinges, in contrast with standard ones, give greater security especially to the doors installed in locations with exit to the outside, eliminating the risk of door manipulation.
Hidden door closer, instaled in the upper part of the leaf, remains completely unnoticed and, in the case of double leaf, the sequence selector is also integrated inside the leaf. Both accessories allow an easy access and greater security.
Fire rated DHTURIA EI290 COBO door is similar to the standard double leaf TURIA door but additionnally it is equipped with:
- 6 concealed hinges,
- ECO MULTIGENIUS hidden door closers.
The DHTURIA COBO door gains three basic features:
a) Higher security level as the hinges are not exposed to any manipulation which is beneficial for external door.
b) Improved hygiene: the oil used for maintenance do not leak out. In consequence there is no risk of oil stains on door leaf thanks to the hidden system.
c) Refined aesthetic: free spaces between leaf and frame have better adjustement.
