The Probrico Matte Black Passage Door Knobs, designed for interior doors, offer reliable closure without a locking feature. These classic colonial knobs with a matte black finish are a perfect enhancement for traditional and contemporary homes.

The Probrico Door Knobs boast several key features:

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

Full Inner Door Knob: The longer riveting position of the inner ball provides greater stability, preventing the ball head from skewing or loosening.

Thick and Firm Latch: The 2.0mm-thick tongue plate material enhances the strength of the door and prolongs its service life, ensuring a mute and impact-resistant closure.

Sturdy Internal Structure: The 65 manganese steel, with a manganese content of 0.9%, offers strong wear resistance and can pass the three-level standard 250,000 wear resistance tests.

Easy Installation: All necessary accessories are included, making the installation process a one-person project. The reversible levers are suitable for both right-hand and left-hand doors, and the adjustable backset of 2-3/8" to 2-3/4" fits all standard door preparations.

In addition to the Passage Door Knobs, Probrico offers other functions, including Keyless Privacy Door Knobs for bathrooms, bedrooms, or rooms requiring a locking mechanism, and Entry Keyed Door Knobs for entrance doors or any door where security is a priority. The Single Dummy Door Knob is designed for decoration and to complete a look, such as for closet doors or French doors.
