Most people assume a lever handle is sprung by default. And in most modern production, that’s true. Yet many functional issues — from sagging levers to worn locks — come from one simple cause: the handle is not sprung, or the user didn’t know the difference.
This guide explains what a sprung lever does, why it has become the modern standard, when it’s absolutely essential, and why some traditional handles are still intentionally unsprung. With clear examples from our own collection.
What does a sprung lever actually do?
A sprung rose or sprung backplate contains an internal spring that keeps the lever automatically level after every use.
That spring ensures:
-
a clean, horizontal return
-
less wear on the lock and spindle
-
a longer lifespan
-
a smoother, more solid feel
With unsprung handles, the lock has to do all the work — often causing early wear, especially with heavy levers.
Why sprung lever handles are the standard today
Most contemporary lever handles are produced with an integrated spring mechanism. They’re reliable, low-maintenance, and suitable for almost every home.
A clear example is our Philadelphia Door Lever — a modern design with a fully integrated return spring to keep the lever perfectly level.
When a sprung lever is absolutely essential
1. Heavy materials (e.g., solid cast iron)
Heavy handles put extra strain on the lock and will sag without support.
Our cast iron lever on backplate with return spring prevents this entirely.
2. Older homes with tired locks
A sprung handle eases the load on a worn lock and restores smooth operation.
3. When clean, modern lines matter
A drooping lever instantly cheapens the look of a door.
Sprung handles stay perfectly aligned at all times.
But not every handle is sprung — and that’s okay
Some traditional designs are intentionally unsprung, not because they are inferior, but because the authentic construction requires it.
A prime example is our nostalgic cast-iron handle set DK8010 — heavy, durable, classic, and unsprung by design.
This means:
-
the handle relies fully on the lock
-
heavy levers may eventually droop
-
the handling matches the traditional aesthetic
Perfect for classic interiors — as long as you know what to expect.
How to recognise a sprung handle
Look for:
-
the term “sprung”, “return spring”, or “spring-assisted”
-
a lever that stays perfectly horizontal
-
slightly thicker rose/backplate construction
When in doubt, ask — it prevents disappointment and returns.
Which do you choose?
Choose a sprung lever if you want:
-
modern doors
-
heavy lever handles
-
support for older locks
-
a clean, level appearance
-
longer lifespan for lock + handle
Choose an unsprung lever if:
-
you want authentic traditional handling
-
the design requires it
-
the handle is light and used infrequently
Both are correct — choose based on your door and expectations.
Final notes: a small spring, a big difference
The spring may be hidden, but it’s one of the most important parts of a lever handle. Choosing the right type prevents sagging, friction, and premature lock wear. A small detail — but with a big impact on daily comfort.
