Overview
A 6-pack of matte black privacy door knobs from Probrico, with a round ball shape and a turn button lock that can be set to sit horizontal or vertical before installation, aimed at whole-house bedroom and bathroom projects.
Probrico rates this knob to ANSI grade-3 and past 250,000 turn cycles, with a stainless steel body and a 5-pin brass cylinder. Buying it as a 6-pack instead of one at a time is the practical selling point, meant to give every interior door in a home the same matte black look in a single order. One detail worth checking first: the strike plate and faceplate are a fixed one-piece unit, not swappable, so an older or nonstandard door frame should be checked against the existing cutout.
