As you know, RS Group acquired Elfa Distrelec in July 2023. In connection with the merger, we are closing our existing warehouse to deliver from an RS warehouse. Our aim is that you are minimally affected by this ongoing merger, and we also take the opportunity to thank you for your patience. Once we are ready, we will be one company and you will benefit from one single website, a combined customer service, a very large product range and additional solutions.
