What is a door thumb turn?

A thumb turn is the small lever or knob mounted on the interior side of a privacy door, used to engage the privacy lock without a key. Standard thumb turns engage and release the lock through a simple twist.

Where is a thumb turn used?

Thumb turns are used on bathrooms, bedrooms, primary bedroom suites, and any interior privacy door — typically paired with an emergency-release feature operable from the exterior.

What is the difference between standard and indicator thumb turns?

Standard thumb turns engage the privacy lock without showing occupancy on the exterior. Indicator thumb turns add a visual cue on the outside of the door — typically red for occupied, white for vacant — used in shared bathrooms and commercial settings.
