simple question about my doors

this might sound dumb im not sure, but can you put a shaved door handle kit on vertical doors?? i don't see why not, but im kinda newbie to all this, so any help will be greatful.

yeah you can, but you need some door popers, and if your door popers are too powerful they can start to mess with your verdical door hinges... what VDK did you go with?
