Unique Rota-Bearing Sprung Rose Mechansim

Our patent-pending mechanism that helps support and control the movement of a lever, for more precise operation.

Smooth operation

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.

Testing and maintenance

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.

Suited for even the heaviest lever

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.

Made for easier fitting

With a fitting jig available, we've made installation easier for the joiners, whilst the mechanism ensures handles sit perfectly horizontal and operate smoothly.
