Our sprung door handles are designed with low-profile roses, so we’ve had to engineer the sprung mechanism so it recesses into your door.
To install any of our sprung door handles, you’ll need to drill a 45mm pocket into the door for the mechanism. If you’re installing the mechanism into a door that’s previously had a handle, you’ll need to use our bespoke retro fitting kit (you might know it as a jig).
This will provide an accurate guide for our 45mm Forstner drill bit, so the hole is created in the correct place. It’ll stop the drill from wandering across – and possibly damaging – the door.
Watch our installation video here to see just how easy it is to use.

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 from our mobile-friendly instructions page.
If you've purchased door handles from us after 27 November 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 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.com.
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.
