The FRAME 40 internal door consists of an ultra–thin aluminium door case of 40mm with no peripheral cover and a framed glass panel of 33mm × 16mm section aluminum profile. The panel moves using adjustable pivot stainless steel hinges. The door has either an elegant square magnetic lock, or a non–locking accessory "ball catcher". Its impressive minimal result is achieved thanks to the square or "T" cross–section decorative aluminum mullions.
