Sprung handle A sprung handle is engineered with a built-in ‘cassette’ that holds a pre-tensioned spring.
This spring mechanism is strong enough to take the weight of the handle and return it to its original position over and over.
You won’t experience any drooping with this style of handle (even if it’s a lever that’s made from weighty solid brass like ours all are), and you can pair it with any latch you like.
We’ve taken a slightly deeper dive into the engineering behind our own sprung handles
here.
Unsprung handle This handle variation is designed without a spring mechanism (something that’s much less important for door knobs).
If your handle is a lever design, it must be installed with a latch that has enough tension to return it to its original horizontal position after use.
Fixed handle Sometimes referred to as a ‘dummy’ door handle, this has no latching or locking function. You can push or pull on it to open or close the door, but it won’t actively rotate or move up and down.
It’s a good choice for internal double doors the fixed handle is surface mounted to the ‘inactive’ door to create a cohesive look.
