*On some earlier models the slots in walls are quite thin, it makes it easier to replace in position by using a flat head screwdriver to 'widen' the slot for the 'runner' to fit in.

*Remember you can remove shelves completely to stand drinks up, we just supply more shelves than needed for people so you have plenty of options.
