Matte Black Interior Door Knobs 6 Pack - Classic Round Privacy Set

Our review of the Haidms 6 Pack Matte Black Door Knobs finds them best suited for homeowners and renters who want an easy DIY upgrade to bedrooms and bathrooms without changing door hardware dimensions. The biggest reason to buy is the combination of a clean, classic matte black finish and a straightforward privacy mechanism that fits most standard interior doors, making it a practical, low-effort refresh. Installation is simple with only a screwdriver required, and the set includes adjustable latches to work with common door backset sizes.

Key Features

• Matte black finish: The elegant appearance blends with both classic and modern decor, instantly updating a room's look without clashing with other hardware.
• Privacy lock: The thumb turn on the inside locks the latch for bedroom and bathroom use, while the outside has an emergency slot that opens with a flat tool.
• Adjustable latch: The latch length adjusts between 2-3/8 in and 2-3/4 in so the set fits most standard door backsets without extra parts.
• Door thickness compatibility: Designed to fit doors from 1-3/8 in to 1-3/4 in thick, covering the majority of interior residential doors.
• DIY installation: Comes with instructions and the required hardware, allowing installation in minutes using a screwdriver.
• 365 day trial support: The seller offers a risk-free 365 day trail and asks buyers to check parts before installation and to contact support for quality issues.

Who It's For

This set is ideal for homeowners, landlords, or renovators who need an economical way to replace or unify interior door hardware across multiple rooms. The classic round shape and matte black finish make it a good match for bedrooms and bathrooms in both modern and traditional interiors. It also works well for DIYers because the kit includes clear instructions and only basic tools are required.

Those who need keyed exterior locks, heavy-duty commercial hardware, or precise matching keyed cylinders should look elsewhere, since this product is a keyless privacy set meant for interior use and customers have reported mixed feedback on functionality and key consistency for similar sets.
