<p>The gauge (1) has a flat and monoblock single part (2) comprising a first part (3) engaged in a vertical through-hole (T) of a strap hinge (P) of a shutter receiving a hinge. The single part includes another part i.e. lower part (4), provided in an extension of the first part and more broader than the first part so as to serve as a stop. The lower part has a through-hole (6), and is shaped for forming the stop at determined distance for providing a drilling function to drill the through-hole in a wall. The single part has a gripping part (5) shaped for allowing holding of the gauge in hand.</p> |
