This should be possible so 1 screw will go through the hole the knob was using and into the new handle.
You MAY be able to avoid drilling 2 holes and drill only 1 by using the existing knob hole. If you are changing your kitchen cabinets from knobs to handles, then you need to drill 2 new holes and fill in the hole from the knob. If your cabinets are wood with no handle or knob, then all you must do is drill through the wood using the template supplied with the handles. Just count how many cabinets you have including the cabinets that do not actually open like the ones under the kitchen sink. You can buy cabinet hardware handles in bulk and save money. The only issue is you now have a hole from the old knob in the cabinet. Replacing these knobs with modern handles is a great way to change the appearance of your cabinets for next to nothing. Most older kitchen cabinets have knobs (one hole) to open them. If you are looking to modernize your kitchen, the cabinets need to be modernized too.
