Key Features:

Strong Knob: The ball head is made of high-density, high-tensile strength materials with minimal impurities, ensuring a more stable and durable electroplating finish that can withstand 72 hours of salt spray testing without corroding or fading.

Full-Inner Door Knob: The extended riveting position of the inner ball provides a steadier and more secure fit, preventing the ball head from becoming skewed or loosened over time.

Thick and Firm Latch: The 2.0mm thick latch plate material effectively reinforces the door's strength and durability, ensuring a quiet and impact-resistant closing mechanism.
