Supplier's note

1. Technical Breakthroughs:

   • 3D Directional Adjustment: Enables precise alignment in uneven door frames (e.g., ±8° tilt in Pro Model).
   • 180° Opening Angle: Doubles standard hinge functionality for full-space access.
   • Zinc & Solid Brass Core: Outperforms industry benchmarks in corrosion resistance (tested for 1,000+ hours in salt spray).

2. Optimal Version Selection:

   • Base Model: Ideal for residential doors (e.g., bathroom or closet) with standard weight requirements.
   • Advanced Model: Suitable for commercial applications (e.g., office partitions) needing enhanced durability and compliance with RoHS standards.
   • Pro Model: Designed for industrial use (e.g., hospital or lab doors) where NSF certification and heavy-duty load capacity (60kg) are critical.

With the Pro Model’s solid brass construction, you can ensure corrosion-free operation in marine environments. Pair its 8° adjustment range with heavy-duty doors to eliminate misalignment issues permanently.
