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.
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
- 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
Although some of our hardware products can be fitted by anyone proficient at DIY, we recommend that our door handles are installed by a qualified builder or joiner.
You can view and print instructions on our mobile-friendly instructions page.
If you've purchased door handles from us after 1 May 2025, these can be used internally and externally, however, only our unsprung handles can be used with standard multi-point locking systems.
Door handles ordered before this date can only be used internally.
When it comes choosing the right size latch, 100mm is best for our door knobs to ensure a comfortable turn (no catching your knuckles on the edge of the door), while 60mm is recommended for our lever handles.
We sell all our door handles and knobs in pairs, except for our recessed door handles which are sold individually.
Our cabinet handles and shelf brackets are sold individually (each bracket will support up to 40kg).
Most of our window hardware has been designed for use with timber windows (you can install the products on aluminium frames too – we just don’t provide the fixings for this). Our Southbank tilt and turn handle is compatible with timber, aluminium and UPVC.
Spare snap-off screws for our cabinet handles can be found on our tools and spares page. For all other spare part enquiries, please email our customer service team at hi@corston.eu.
Yes, you can use our medium and large cabinet handles as appliance pulls. They're made of solid brass so they won't warp or deform over time, even when used on heavy doors.
