Our flat-fronted Onslow door knob is a contemporary alternative to our beehive design.
The knob is unsprung, which means you can use it with an existing sprung latch. To make sure it stays easy to turn, we'd recommend using a lightly sprung latch.
There’s also no danger of it coming away in your hand – we’ve engineered the rose and knob to be inseparable.
Bronze is our boldest finish, but it isn’t shiny or bright, so it has a subtle side to it too. It’s a deep matt brown colour that’s almost black in some lights.
- Made from solid brass

- Designed for use with a tubular latch or mortice lock

FAQs
We recommend using a professional to fit all Corston products. Electrical items must be installed by a qualified electrician.
If you opt for our unsprung handles, a strong latch will work best with our lever handles to prevent drooping. You can use a lighter latch with our knobs to ensure they're easy to turn.
They'll support 40kg per bracket.
