We work with two different densities. Depending on the type of project, the chains can hang symmetrically or asymmetrically. The perfect symmetry. Homogeneously aligned rows of chains. Suitable for most uses The asymmetrical option. For projects that require higher opacity. Kriska 78 strands per linear meter of rail. Snina 100 strands per linear meter of rail.
