Use 37 folding where a full folding wall is too much — wardrobes, kitchens and narrow passages. This half folding profile belongs to a complete door profile family — NICE door profiles are universal profiles: the same frames build eight door types, so swing, sliding, hanging and folding doors in one project share one sightline and one finish.
