Tips

To ensure a secure installation, always use K2 rail connectors when extending the SolidRail Light and finish exposed ends with K2 end caps. The rail's mill finish is naturally corrosion-resistant, but avoid contact with dissimilar metals to prevent galvanic corrosion. For optimal load distribution, space the rails according to the module manufacturer's guidelines and local wind and snow load requirements.
