Internal Thumb Turn Locks

Internal thumb turn locks provide a simple and effective privacy solution for interior doors such as bathrooms, WC doors and bedrooms. Designed to work with bathroom mortice locks, these fittings allow the door to be securely locked from the inside using a convenient thumb turn. Ideal for areas where privacy is required rather than high-level security, internal thumb turn locks offer smooth and reliable operation for everyday use.

An internal thumb turn and release lock consists of a thumb turn fitted on the inside of the door and an emergency release on the outside. The thumb turn operates the privacy bolt within the mortice lock, allowing the door to be locked quickly and easily. The external release ensures the door can be unlocked safely in case of emergency, making these locks particularly suitable for bathroom and WC doors.

Available in a variety of finishes to match door handles and other interior hardware, internal thumb turn locks for doors provide both practicality and a coordinated appearance. Manufactured from durable materials and designed for straightforward installation, they are a reliable solution for new door installations or replacement projects where simple privacy locking is required.
