Hayn concealed thread cable rail systems were designed with a modern and minimalist look in mind.  Elimination of any exposed or visible threads was the key attribute to the design, while focusing on the reduction of physical size.  These systems allow for ease of installation with supporting Wall Eye Options for stair angle compensation and Wood Inserts for anchoring into wood posts.  For extended length runs, these systems include a concealed thread intermediate turnbuckle system to ensure adequate tensioning of the cable system can be achieved.
