The HST door is well suited for up to 6 m wide openings, that require a lot of glass space with minimal visual obstructions. It is a comfortable solution, because it utilizes large window panes, which provide large unobtrusive glass surfaces with a great view. Ball bearings make sliding the movable casement easy. The fixed and the movable casements are installed separately on two levels. The design is suitable for large passageways.
