Probrico Interior Door Knob Set – Black Round Ball, Hallway & Closet, 6-Pack

Elevate interior doors with Probrico black round ball knobs

Designed for everyday life, this Probrico knob set brings a modern touch to hallways, closets, and pantry doors without locking hardware. The matte black finish resists fingerprints and corrosion, staying attractive with less maintenance. The rounded ball handle feels natural in hand, offering a comfortable grip that suits long corridors or frequent door passages.

Key durability and security come from ANSI Grade 3 certification and a brass cylinder with five pins, delivering smooth operation and added resistance to wear over time. While not a locked knob, the reinforced latch is built to withstand impact and frequent slamming, making it a dependable choice for high-traffic rooms.

Designed for flexible interior use

Passage knobs are ideal when you don’t need a key, such as a closet, hallway, or pantry. This Probrico set pairs a modern black finish with a round ball handle and a comfortable, nonabrasive edge that keeps hands safe during quick door runs.

Installation is straightforward on standard door preparations. The latch backset is adjustable from 2-3/8" to 2-3/4", and it fits doors 1-3/8" to 1-3/4" thick. Universal handing means it works on both right- and left-handed doors, reducing the guesswork for DIY setups.
