finzone09 frameless tempered glass.
The finzone09 frameless tempered glass have no side frames and therefore no side hinges. They easily slide left and right along teflon guides above and below. As each door reaches the end of the guides, there is a swivel-point so that the doors can open inwards or outwards (as specified) to enable the whole width of the opening to be used for access.
Look the video below to see how it works.
