The Straightaway Telescopic 4 Leaf system is smooth and durable and ideal for four sliding doors, required to move in the same direction, to make more efficient use of building space with wider passageway options than single sliding leaf doors. The space saving design uses a heavy duty toothed belt and pulley to allow multiple doors to be linked together so that they can all be neatly aligned behind each other, when opened. Can be used with Straightaway and Eternal 130, 180 & 250 systems
