Round Privacy Door Knob (2 Pack) - Keyless Black Privacy Locks

Our review of the Probrico 2 pack round privacy door knob finds it best suited for homeowners or renovators who need a simple, durable privacy lock for bedrooms and bathrooms; the single biggest reason to buy is its straightforward, keyless privacy function combined with a solid stainless steel build that resists rust and wear. Installation is quick for a typical DIYer, and the black finish gives a modern appearance. The unit is ANSI Grade 3 rated and promises long service life, though a few users reported inconsistent lock direction or occasional mechanism issues.

Key Features

• Privacy Function: The keyless thumb turn and push-button lock provide private, tool-free locking for bathrooms and bedrooms.
• Adjustable Latch: The latch supports backsets of 60mm (2-3/8in) or 70mm (2-3/4in), so it fits most standard interior door preparations.
• Door Thickness Compatibility: The set fits doors 35 to 45 mm (1-3/8in to 1-3/4in) thick, covering common residential interior doors.
• Durable Material: Stainless steel construction with a black plated finish resists rust and delivers long-term strength.
• Security Build: Conformed to ANSI Grade 3 with a 5-pin brass tumbler and a solid column security bolt to resist sawing.
• Easy Installation: The design has no small fiddly parts and ships packaged individually to reduce damage risk during delivery.

Who It's For

This privacy knob set is aimed at homeowners, landlords, and contractors who need reliable, keyless locks for interior rooms such as bathrooms and bedrooms and want a modern black finish. It is a practical choice for straightforward retrofit jobs where a standard round privacy knob and adjustable latch are required.

Those who need heavy commercial-grade security, keyed entry, or nonstandard door thicknesses should look elsewhere. Also consider other options if exact lock orientation matters to you, since some users reported inconsistent locking direction from unit to unit.
