The particularity of this ballast is that the lead remains sliding around the main line with a simple movement; may be removed and / or replaced with another grammage very quickly and with the advantage that on the main line does not remain other components of the ballast.
Lastik is an inventive device that, says its makers, “is a simple innovation in the field of interchangeable weights”. The product consists of a lead with a longitudinal slot through which flows the main line. On the two edges of the lead are two cavities into which an elastomer can be fitted. When you want to change the weight on the line, you only need only release the elastic and the line will be completely free. Lastik is available in the following weights: 2g, 3g, 4g, 5g, 8g, 10g, 12g, 15g, 20g, 25g, 30g, 40g, 50g, 60g, 80g and 100g.
