Premium privacy, modern style

Meet Plustool's matte black privacy door knobs with locks—an 8-pack designed for interior rooms like bedrooms and bathrooms. Crafted from premium stainless steel with a matte black finish, these knobs resist rust and fingerprints while maintaining a refined, contemporary look. The round ball shape offers a comfortable grip and smooth contact with your hand, reducing snags during busy daily use.

Durable, thoughtfully engineered

Built for reliable privacy, the assembly is ANSI Grade 3 certified and rated for up to 250,000 cycles. The solid column security bolt adds anti-sawing protection, while the 5-pin brass tumbler cylinder supports steady operation. The electro-plated finish guards against corrosion, helping the hardware retain its sleek appearance over time.
