Symbio's concealed door hinges remain flush with the wall mount and are easy to adjust on their 3 axes, allowing for an aesthetically perfect thermal and acoustic insulation. Doors can be adjusted vertically, transversely and in depth on both the door's and frame's side of the hinge.

Symbio's patended adjusting mechanisms , and their semplicity of operation, are the results of La Floida's constant product research, development and innovation.
