The Unique Rota-Bearing Sprung Rose Mechanism

The Joseph Giles unique rota-bearing sprung rose is a mechanism which is concealed within the rose of a lever handle. The Sprung rose helps to support and control the movement of the lever, allowing for a more precise operation.

Designed and made in Britain.

The Joseph Giles unique rota-bearing sprung rose allows for the seamlessly simplified application of even our heaviest pair of solid brass handles, while the concealed horizontal stop ensures that our lever handles always sit perfectly horizontal. Our unique sprung rose design brings smooth, silent and flawless operation to all Joseph Giles levers.


Designed to deliver a flawless performance, the unique rota-bearing sprung rose has been tested to operate for over 200,000 cycles with no wear or deterioration to its function, making it completely maintenance-free for its lifetime.

Flawlessly Engeneered
Strong - Sprung Rose


As our handles are made from solid brass, they are often too heavy for general latch mechanisms. One of the most beautiful things about the unique rota-bearing sprung rose is that it allows even our heaviest pair of levers to sit completely straight and maintain a centrally fixed axis of rotation.


The mechanism allows for much easier fitting of our handles on any door that has a pre-existing latch.
