Spring Unit Cassette

This retracts the lever to its normal position after use.

If you are using heavy sprung locks or latches you won't need one of these, however if you are installing our handles or knobs to standard locks it's a good idea to ensure the lock or latch is not over worked.

These are low profile and will fit under our handles and knobs without alteration to your door.

It converts unsprung handles to spring action. It is cut into the door below the back plate either on one or two sides. So if you have a poor lock and you want our handles to work perfectly this is the answer.
