The Securiturn is a convenient, safe and secure removable thumb-turn for double cylinder locks, which can be easily removed when the building is secured, using a release key. The innovative design allows new and existing double cylinders to have the everyday convenience of the thumb-turn which can be removed when the premises are unoccupied.

The Release Key is used when it is necessary to remove the Securiturn from the cylinder. Simply slide into the cylinder behind the key.
