Easy installation for solar panels: quick and straightforward setup saves time and labor costs. Designed for hassle mounting on various roof types without specialized tools. Wide compatibility and panel fit: engineered to fit solar panel frame heights of 30 mm, 32 mm, 35 mm and 40 mm with a material thickness of 4 mm, offering broad compatibility across different photovoltaic system configurations. Long lasting aluminum alloy construction: built from robust aluminum alloy with an electroplating process for oxidation resistance. This black end clamp maintains integrity while withstanding extreme weather conditions. Strong performance in harsh conditions: provides resistance against stressors, delivering reliable performance and secure panel holding through diverse climatic challenges. Practical use scenarios: residential roof installations where panels have different frame heights. Retrofit projects replacing older clamps on systems with varying frame heights. Outdoor commercial or industrial solar arrays in challenging climates requiring durable, weather resistant mounting.
