## Description

For bedrooms, bathrooms, and other interior rooms that need a privacy lock without a key, the LANSTE 10-pack provides a matching set of matte black knobs with an inside thumb turn and an outside emergency release.

A standard non-locking passage knob suits doors that should remain freely accessible. This privacy style adds a lock for rooms where occupants want more privacy while keeping an emergency release accessible from outside.

With ten knobs in the pack, it’s a practical way to outfit several interior doors with a consistent modern finish. The adjustable latch is designed for common residential door dimensions, and the reversible design accommodates left- or right-handed doors.

## Quick sizing guide
The adjustable latch fits a 2-3/8" or 2-3/4" backset and doors 1-3/8" to 1-3/4" thick. Check those measurements against the door before installation. The latch plate is non-removable, so its configuration is part of the fit. The knobs are intended for indoor use on bedroom, bathroom, office, and other interior doors.

Installation uses a screwdriver, and the package includes installation hardware and a strike plate. The reversible design supports either door handing, making these knobs suitable for replacing existing interior door hardware as well as outfitting multiple doors in a renovation.

## What stands out
The privacy function is straightforward: turn the lock from inside, then use a coin or flat screwdriver at the outside emergency release if access is needed. That keyless setup is useful for a bathroom or bedroom where privacy matters but an emergency release is also important.

Stainless steel construction and a matte black finish give the set a modern look that can coordinate across several rooms. The product is described as rust-resistant and corrosion-resistant for humid environments. Its round shape and black finish also pair with both contemporary and traditional interiors.

Customer feedback often praises the knobs’ quality, durability, and ease of installation. Some buyers report mixed functionality and say the lock operates in the opposite direction from what they expected, so pay attention to the lock orientation when installing each knob.
