Wide Compatibility: This stainless steel roof rack is compatible with ProMaster, Boxer, Jumper, Ducato, and Movano vans. It is installed with a mushroom-head base and fits over 90% of vans and motorhomes. No Tool Installation Required: The solar panel bracket is designed for snap-on installation; no drilling is necessary to avoid damaging the vehicle's original waterproofing. With included stainless steel screws and a non-slip washer, it can be installed in just 15 minutes, eliminating the need for heavy professional tools and unnecessary costs. Good stability: This roof rack mounting kit, in addition to using standard van roof rack brackets, features a unique double-track groove design that also ensures the stable attachment of solar panels, preventing loosening or detachment while driving. The overall appearance is elegant and sophisticated, adding a unique sense of technology to the vehicle. 304 stainless steel: This roof rack is made of 2mm thick 304 stainless steel, which is processed using forging technology. The surface is brushed to improve wear resistance, making it more durable and suitable for long-term use. Its excellent corrosion resistance and antioxidant properties effectively prevent the roof shelf from corroding and being damaged in various environments, preserving its appearance and functionality. This makes it an environmentally friendly and efficient choice for roof shelving.
