By utilising the identical fixing holes already in your door, superseding your door handle with Ultion Nuki is uncomplicated. We can easily replace all standard UK push-down door handles. It accommodates lever handles where the space between the handle fixings is 215mm, 211mm and 122mm. The span between the middle of the handle (spindle) and the barrel (keyhole) should be 92mm. The flexible design of the Ultion Nuki handle also means that should you switch your door or decide you are going to move house, you can continue to use it on the new door without needing to purchase a new handle.
