Harmonica doors – Aluminum




The harmonica door is the best solution for opening the interior and exterior of the property together. When open, the collapsed segments take up little space, so they are preferred for high-end houses and large areas suitable for hospitality. MARSHALL makes harmonic doors from a sturdy aluminum structure. The apparent width of the frame has a surprisingly thin appearance.
