## Description

## How it fits
Some interior doors need a straightforward handle, bedrooms and bathrooms often call for added privacy. These Plustool round knobs combine everyday door hardware with a push-button privacy lock, bringing the same matte black finish to multiple rooms in one 10-pack.

The adjustable latch fits doors 1-3/8" to 1-3/4" thick and can be set to either 2-3/8" or 2-3/4". The reversible design works for left- or right-handed doors, making it easier to keep a consistent look across rooms with different door orientations. For a renovation or a coordinated hardware update, a multipack offers a uniform alternative to choosing knobs one room at a time.

## Pros
A round ball shape and matte black finish give these knobs a modern, simple profile that pairs naturally with contemporary interior hardware. Stainless steel construction and an electroplated finish are intended to help resist corrosion and fingerprints, so the surface is suited to regular indoor use. The rounded form also avoids sharp edges at the handle itself.

Privacy is operated from inside by turning the button. The outside emergency release can be opened with a coin or screwdriver, a practical feature for bedroom and bathroom doors. The push-button mechanism provides a keyless way to secure a room while keeping the exterior release accessible when needed.

Installation is designed for a screwdriver, and instructions are included. The latch is adjustable, and the knobs are reversible for either door hand. Buyers often praise the matte black appearance and straightforward installation. Feedback on the locking mechanism, fit, and build feel is mixed, while some customers say the knobs function as intended. Those varied impressions make it useful to match the latch settings carefully to the door during installation.
