The Probrico Door Knobs offer several key features:

Strong Knob: The ball head is made of high-density, strong tensile strength, and low-impurity materials, ensuring stable electroplating quality that can withstand a 72-hour salt spray test without corrosion or fading.

Full Inner Door Knob: The riveting position of the inner ball is longer, providing stable firmness and preventing the ball head from skewing or loosening.

Thick and Firm Latch: The 2.0mm-thick tongue plate material effectively enhances the strength of the door, ensuring a mute and impact-resistant operation.

Sturdy Internal Structure: The 65 manganese steel material with a 0.9% manganese content offers strong wear resistance and stability, passing the 250,000-cycle wear resistance test.

Easy Installation: All necessary accessories are included, allowing for a one-person installation project. The reversible levers are suitable for both right-hand and left-hand doors.

Comfortable Touch: The round ball knob design provides a comfortable grip without any sharp edges.
