<p>The device is assembled of a rectangular plastic grid of a suitable size and several joint elements. The joint element has a hook-shaped upper area with a triangular extension at the lower end. The grid is joined to the element by using small hook shaped projections protruding from the front surface of the element, while the joint element itself is attached to the window box with the main hook. The triangular shape of the extension keeps the grid in a sloping position in relation to the window box facilitating the tendrils to grow in a natural curve supported by the grid from below.</p> |
