Hi and thanks in advance.
I have purchased a passage set door knob (https://www.bunnings.com.au/ikonic-brushed-nickel-ruby-passage-set_p0199993) and am hoping to change over from an old one. The hole needed for the new one is larger than the existing. I have a drill bit for the right size hole but how do I line it up and make sure it’s in the right place? It looks from the instructions like the new knob only has screws in to the door on one side and also horizontally so the existing screw holes shouldn’t be a problem. Is that right? Thanks
