Our Poplar design is our take on the classic Victorian beehive knob.
We’ve streamlined things, giving it a flatter knob and, in this case, a low-profile, long backplate that’s designed for use with a Euro cylinder lock. It’ll work well in period properties with a contemporary edge, or by bringing a traditional touch to new builds.
The knob is sprung, which means you don’t need to rely on the latch’s spring for its movement. We’ve opted for a light spring, so it takes very little effort to turn.
There’s also no danger of it coming away in your hand – we’ve engineered the backplate and knob to be inseparable.
Polished nickel is our answer to chrome. It’s a bit warmer, which we think is more versatile, so you can use it with warm or cool colour palettes.
- Made from solid brass
- 4mm backplate with screwless ‘front’ side
- Super smooth turn thanks to self-lubricating, high-tolerance bushings
- Longer handle neck for a comfortable grip
- Designed for use with Euro mortice locks with a 72mm C-C spacing (cylinder not included)
- Engineered to fit all standard door thicknesses
- When retrofitting, you’ll need to use our door handle installation tool
- Suitable for interior and exterior doors
- Sold in a pair

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.
