Probrico, a professional home hardware manufacturer with over 10 years of experience, is a brand owner targeting US customers. The company offers a wide range of door knobs, handles, and cabinet hardware, promising modern design and great value to provide a perfect home experience.

Probrico's door locks feature reinforced deadbolts that are resistant to impact and can withstand the force of slamming doors. The Passage Knobs, designed for interior doors, offer reliable closure without a locking feature. The classic colonial design with a matte black finish complements traditional and contemporary homes.

The Probrico Door Knobs boast several impressive features. The ball head is made of high-density, high-tensile-strength, and low-impurity materials, ensuring stable electroplating quality that can withstand the 72-hour salt spray test standard without corrosion or fading. The full-inner ball design with a longer riveting position ensures stability, preventing the ball head from skewing or loosening.

The latch mechanism is built to last, with a 2.0mm-thick tongue plate material that enhances the strength and durability of the door. This feature also ensures a quiet, impact-resistant operation, allowing users to slam the door without fear. The internal structure is made of 65-manganese steel, with a manganese content of 0.9%, providing strong wear resistance and passing the 250,000-cycle wear resistance test.

Probrico's door knobs are easy to install, with all necessary accessories included, making it a one-person project. The rounded ball handle design offers a comfortable grip, with no sharp edges. The universal, reversible operation knobs are suitable for both right-hand and left-hand doors, and the latch has an adjustable backset of 2-3/8" to 2-3/4" to fit all standard door preparations, accommodating door thicknesses from 1-3/8" to 1-3/4".

In addition to the Passage Knobs, Probrico offers other door knob functions, such as 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.

Probrico's door knobs are made of stainless steel with a black finish. They are designed for use on interior doors that do not require locking functionality, such as hallway, closet, or passage doors. The products are ANSI Grade 3 Security-compliant, ensuring quality, strength, security, and durability. Probrico offers a quality guarantee, promising to refund or replace any item with quality problems.
