It is suitable for residential, commercial, and industrial installations that demand a robust connection on wooden structures or hybrid roof assemblies. This kit combines an M12x250 double thread screw with a sealing washer engineered to provide optimal protection against water ingress. The 250 mm length, together with the wood thread and metric thread, ensures a strong grip on the substructure while offering a secure anchor point for the SingleRail profile. The dual-thread design delivers efficient mechanical load transfer, enhancing system stability under the typical stresses of solar installations, especially in regions exposed to high winds or significant snow loads. The integrated sealing washer, specifically sized for photovoltaic mounting, forms a long-lasting moisture barrier that preserves roof integrity while securing the entire installation. Thanks to its design, the Climber Kit M12x250 greatly simplifies on-site installation. Installers benefit from a stable support point, adjustable height, and precise SingleRail alignment, accelerating the assembly of the PV array and reducing the risk of installation errors. Its full compatibility with the K2 SingleRail system ensures perfect mechanical coherence between components, avoiding the shortcomings of generic fasteners. This consistency improves global system resistance and reduces long-term maintenance needs. In residential applications, this double thread screw is highly valued for its reliable sealing and clean installation process, which helps protect the roof structure while providing a solid attachment for photovoltaic modules. In commercial or industrial projects, it stands out through its high load capacity and ability to support long rail runs, particularly on large pitched roofs. The kit is also well suited for older buildings or irregular wooden structures, where the flexibility of the dual-thread design offers a significant advantage. Compared with other fastening options in the range, the M12x250 Climber Kit distinguishes itself through its reinforced diameter, optimized length for superior mechanical performance, and high-efficiency sealing washer, giving installers a more durable, stable, and effective solution for all SingleRail-based photovoltaic installations.\u003c\/p\u003e","brand":"K2 Systems","offers":[{"title":"Default Title","offer_id":48549820170340,"sku":"MSTK21068","price":8.28,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/0146\/9028\/files\/0f842a1d3334d81cbd4335cf417515b4.webp?v=1781169027","url":"https:\/\/www.ecostal.fr\/products\/k2-singlerail-double-threaded-screw-climber-kit-m12x250-with-washer-d_x005f_x0019_-seal-pu-1-50-1200","provider":"Ecostal France","version":"1.0","type":"link"}
