<p>The two lengths of L-shaped angle profile (1a, 1b), include holes (4) for stub shafts. Locking rods (3) are provided. These are torsionally-rigid, and have ends with stub shafts (8a, 8b) fitting the holes (4). Each rod has a handle (10) built onto it, allowing it to be rotated about its axis. Near the ends of the locking rods, eccentrics (9) project out radially. Stub shaft lengths are unequal. At ends of the angle profiles, remote from the first stub shaft hole, further stub shaft holes (6) are provided. Two metal reinforcing base strips (2), are provided for fastening to the opening leaf.</p> |
