All Trustlock levers have a unique design. They can easily be converted to a different appearance or function simply by changing the outer cover ring.
Trustlock rosettes have been cleverly designed for ease of fitting and can be converted from a screw-on outercover ring (standard) to a Push-on, simply by placing a rubber "O" ring in a groove that is present along with the thread on every rosette. This allows a range of different outer cover rings to be fitted which gives a variety of different appearances, using the same lever.
It even allows a standard passage set to be converted to a Privacy function simply by changing the cover ring and adding our specially designed privacy latch assembly.

See the range of rosette cover rings in the product range menu.
