In solar PV installation, varying roof tile heights often pose a challenge. As a leading solar mounting manufacturer in Xiamen, we have developed two highly popular adjustable aluminum hooks: 37#B and 37#A, designed to adapt to various complex roof structures with ease.

37#A is our "all-rounder" designed for roofs with significant height variations. Its standout feature is the extensive adjustment range, making it a perfect fit for various tile profiles.

Core Advantages:
With simple bolt adjustments, it compensates for uneven roof surfaces, ensuring a flat and aesthetic PV array while minimizing on-site cutting and drilling.

37# B hook is a classic in our lineup. While maintaining robust support, it offers convenient vertical adjustment, making it a favorite in the European, American, and Southeast Asian markets.

Core Advantages:
The "Golden Pair" of 37# and the SR series rail not only speeds up installation but also significantly enhances the system's wind and snow load resistance.

Our 37#B and 37#A hooks are engineered not just for flexibility, but also for industrial-grade durability. Utilizing high-strength AL6005-T5 aluminum with an advanced anodized finish (over 10μm), these hooks maintain exceptional corrosion resistance—even in high-salinity coastal areas or extremely humid environments. Coupled with SUS304 stainless steel fasteners, our Solar mounting systems are designed for a service life of 20+ years.
