Probrico Antique Brass Privacy Door Knob Set - Keyless Lock

In this review of the Probrico 8 Pack Antique Brass door knob set, the bottom line is simple: this is a practical, budget-friendly privacy knob ideal for bathrooms and bedrooms. The set stands out for its antique brass finish and straightforward, keyless privacy function that locks from the inside with a push or turn, and opens with an emergency release from the outside. For homeowners replacing multiple interior knobs or fitting a rental property, the pack delivers consistent appearance and reasonable security without specialist tools or complicated steps.

Key Features

• Privacy Function: Locks from the inside with a push or turn button and includes an emergency release on the exterior to handle accidental lock-ins.
• Adjustable Latch: The latch supports backsets of 60mm (2-3/8in) or 70mm (2-3/4in), making it compatible with the most common interior door preparations.
• Door Thickness Compatibility: Fits doors 35 to 45 mm (1-3/8in to 1-3/4in) thick so it works across standard interior doors without extra hardware.
• Durable Construction: Stainless steel construction with an antique brass plated finish resists rust and provides long-lasting appearance and function.
• ANSI Grade 3 Performance: Built to ANSI Grade 3 standards with over 200,000 cycles and a 5-pin brass tumbler for dependable everyday use.

Who It's For

The Probrico privacy knob set is best for homeowners, landlords, and contractors who need multiple matching interior privacy locks for bathrooms and bedrooms and prefer a keyless privacy option for convenience. It is also suited to DIYers who want a quick swap with minimal fuss, since installation is straightforward and the pack is supplied individually to avoid damage.

Those who need a high-security exterior lock or a knob with a removable square latch plate should look elsewhere, as this set is designed for interior privacy use and the latch plate is fixed. If you require keyed entry that matches other exterior locks, choose a keyed entrance set instead of this privacy set.
