Zusammenfassung: | A conventional spanner (1) with double-end open jaw (4) and fixed forks (5) has profiled sleeve (6) clamped on one face at one end. The sleeve has an open jaw (9) to lie over the jaw of the spanner head (3), but only partly covering the opening, with its forks (8) parallel to, and directly over the forks of the spanner jaw. The opening between the forks of the sleeve is narrower than the spanner opening, and the sleeve slides up or down on the hand hold (2) of the spanner, either to a position over the original head or away from it. The sleeve is of transparent material, such as flexible plastics. ADVANTAGE - Versatile design and easy handling. |
