Good to know... Thinking that 3.5-4" spacing will do the job right. Leaning more towards the 4" spacing though. Just need to make sure the drip tray will work well with that spacing (it should, since the taps will be a max of 8" apart)... My tray is a 12"x5" model... I'm using magnets to adjust the height of it, so that I don't need to drill more holes in the fridge. Using rare earth magnets, it will easily support a 24oz bottle of soda and not even flinch. :rockin:
