EVVA OKZ Oval WC Cylinder

The EVVA OKZ Oval WC Cylinder is a robust, oval-profile privacy cylinder designed specifically for bathroom and toilet doors. It is an ideal solution for situations requiring secure thumbturn operation from the inside and reliable emergency access from the outside, such as in public toilets, offices, or family homes.

The external side features a slot-operated turn (compatible with a coin or screwdriver) with a clear red and white indicator to show occupancy at a glance. For safety, this allows quick emergency access if someone becomes locked inside. Please note that the cam is engineered specifically for WC privacy locks, operating on a 180° rotation from 3 o’clock to 9 o’clock.

Constructed to high standards, the cylinder offers 30-minute fire resistance up to 821°C and is supplied complete with a connecting screw. Fitting instructions are available on request.
