Cylindrical Knob Locks for Interior Doors

Knob locks are one of the most common types of door hardware in commercial and residential buildings. Easy to install, widely available, and compatible with standard door prep.

A Practical Choice for Low to Mid Traffic Doors

Interior offices, storage rooms, restrooms and utility spaces are where knob locks work best. They handle regular use well and are simple to rekey or replace when needed.

Door Knob Locks in Every Function

Passage, privacy, keyed entry, classroom, storeroom - our door knob locks come in all standard functions so you can match the right lock to each door in the building.

Cylindrical Knob Locks With a Standard Fit

Our cylindrical knob locks are designed to fit standard door prep, which means straightforward installation with no extra drilling or modification in most cases.

Knob Locks as Part of a Larger Hardware Package

For projects where lever locks cover the main corridors and common areas, knob locks are often used on secondary doors to keep costs balanced without mixing hardware quality.

Available in Multiple Finishes

From satin chrome to oil-rubbed bronze, our knob locks come in finishes that match the rest of your door hardware for a consistent look throughout the space.

Passage, privacy, keyed entry, classroom and storeroom are the most common. The right function depends on what level of access control the door needs.
