Our colored interchangeable struts are a easy way to customize your HEATKILLER® Tube Series reservoir. The struts are made from solid aluminum. The colored versions have a high end anodically oxidized finish. Delivery includes four struts. One of them is designed to hold a LED strip. Corresponding LED strips are available separately.Please be careful to choose the correct strut length for your tube. The name of your HEATKILLER® Tube Series tells you its length, for example a HEATKILLER® Tube 100 requires 100mm long struts.Technical data:Length: 100mmMaterial: AluminumColor: natural
