I cannot imagine having to use the IKEA rail system with their plastic legs - it's just so difficult! I was reviewing the installation guide for tall pantries - there are 2 tall - BIG AND HEAVY! - pantries on this project. So many points to adjust for level - each leg! With my custom base system, I set the height - totally arbitrarily - it can be whatever it needs to be. Look -
I shoot that laser all around the room - all I have to do is attach that base to the wall at the back - adhesives and screws to the studs or the bottom plate - 'side-to-side' levelling - even across 12' - DONE! Then I ensure 'front-to-back' level -approximately every 2' I install a levelling foot - and finished! It's easy, stress free, and no risk of damaging any cabinetry! All the cabinets are tied together with screws and pressed against the wall as a single unit - a straight line. It is very important that all the cabinets faces - doors and drawers - be co-planar, regardless of the wall behind them! That will ensure the best look.
We will finish the project with some custom detailing and this kitchen will look like a million bucks!
