The main difference lies in the thickness of the foam used. There are three versions available: 1 mm, 1.5 mm, and 2 mm. The standard cork layer is 3 mm thick – this applies to all standard options. However, upon special request, we can produce spacers with cork of a different thickness, tailored to individual requirements (simply contact us by email).
Additionally, the spacers come in various lengths and weights, making it easy to match them to specific needs.
