Cavity Privacy Locks

While these locks provide excellent privacy and latching capability, they are not designed for high-security applications like exterior entry doors. The cavity privacy locks are specifically engineered for internal use to prevent accidental entry into bathrooms or bedrooms. For exterior sliding doors, we recommend installing a dedicated patio bolt or a sliding door mortice lock for robust security.

Choosing the right cavity privacy lock depends mainly on your door's thickness and the existing cutout (if replacing an old lock). Our round cavity privacy locks are designed to fit standard Australian internal doors with a thickness between 35mm and 50mm. You should also consider the finish, matching your sliding door hardware to your swinging door handles creates a cohesive look throughout the home.

To install or replace a cavity privacy lock, you need to measure the door thickness to ensure the lock body fits. If replacing an existing lock, measure the backset (distance from the door edge to the centre of the spindle) and the diameter of the existing hole. Our locks generally suit a standard 54mm cross-bore hole and a 60mm backset, making them a great retrofit solution for many standard doors.

No, our cavity privacy locks are non-handed. This means the latch mechanism and handles are reversible and can be installed on doors that close to either the left or the right. This simplifies the ordering process as one kit suits all standard sliding door orientations.
