Matte Black Door Knob with Lock and Key - 6 Pack, Secure Interior Fit

In this review the HOSOM 6 pack matte black door knob stands out as a practical, value-focused option for homeowners and contractors who need multiple keyed entry knobs for interior doors. The biggest reason to consider it is the combination of simple installation and a dual safety design that lets one side lock with a turn button while the other locks with a key, making it a useful choice where basic privacy and keyed access are needed. The reviewer found it especially useful for laundry rooms, bedrooms, and bathroom doors where a durable, modern-looking knob is wanted without a high price tag.

Key Features

• Dual Safety: Provides a turn-button on one side and a keyed lock on the other so you can secure a room from both sides depending on need.
• Door Compatibility: Adjustable latch fits 2-3/8' or 2-3/4' back sets and works with doors 1-3/8' to 1-3/4' thick, covering most interior installations.
• Premium Material: Constructed from heavy-duty, rustproof stainless steel with ANSI Grade 3 certification for everyday durability.
• Modern Finish: Matte black finish gives a simple, contemporary look that integrates well with many interior styles.
• Easy to Install: Assembly requires only a screwdriver and can be completed quickly, saving time during multi-door installs.

Who It's For

This set is best for homeowners, landlords, and small contractors who need several matching keyed entry knobs for interior doors such as bedrooms, bathrooms, laundry rooms, or utility closets. It suits projects where a modern matte black look and straightforward installation are priorities.

It is less appropriate for exterior front doors or locations demanding high-security hardware; although ANSI Grade 3 offers basic strength, those needing commercial-grade or high-security locks should look for higher grade certifications and heavier deadbolt solutions.

Pros & Cons

Pros

• Easy installation that typically needs only a screwdriver and minimal time per door.
• Good value for a 6 pack, ideal for multiple doors in one project or rental property refreshes.
