Plastic patio door 4000x2000 mm Four-leaf with central opening

Windows for elite apartments and houses. How does it work? The operation of this mechanism is very simple: when the handle is turned 90° counterclockwise, the sash opens in a tilt mode (tilt and turn). When the handle is turned 180° counterclockwise, the sash is parallelly shifted inside the room with subsequent sliding along the guides. The possibility of opening the sash in two positions provides additional convenience - the possibility of ventilation with partially closed doors and ease of management - the system is controlled in two positions with one handle. The tilt-slide system can be laminated under the texture of wood or in a smooth base. Hardware binding around the perimeter of the sash ensures reliable clamping. The hardware can be of both window type - with a one-sided handle, and door type - with a one-sided or two-sided handle with a key lock.
