The triple snare lock for a Basle drum has three separately adjustable snare regulators. The lock is of metal, metal alloys and/or refined metals. The first regulator (c) moves in a stirrup. Through drawing the snares, which are drawn downwards, the adjustment screw (c1) locates on the stirrup and can thereby be well adjusted. The second regulator (d) moves in the hollow space of the first regulator and is screwed with the second adjustment screw (d1). The third regulator (e) moves like the second in the hollow space of the second and with the adjustment screw (e1) applies traction to the snares. The fourth screw (f) is for fixing the three other regulators.
