The NM Hyper Meta is designed to be mounted on both bearing batten and untreated plank. Its design follows the shape of the roof tile, allowing for installation without altering or moving tiles. The height can be adjusted using a pre-assembled screw. Meta is delivered fully assembled - no preliminary work is required. When mounted on a rough plank, the hole pattern in the lower part is used, which is designed for the NM Wood Screw. If the tile shape differs from the fastening, alterations may be necessary. 30-year warranty (provided the user follows the installation instructions and uses Nordmount materials)
