The argenta® invisible pro XS-4 is a concealed, compact, budget-friendly, simple, and adjustable hinge which is sold only in bulk. This new series of invisible hinges is aimed mainly at professional large-scale users. With this universal hinge, the screws aren’t visible and it has an opening angle of 180°. A great advantage of this hinge is the 23mm depth, which allows an easy installation in small door frames.
