pieces you will need to order:
24" cabinet
24" deep drawer (for the pull out part)
however many internal drawers you want along with corresponding rationell drawer fronts.
the template comes in any rationell deep drawer front. so if you're using one anywhere it will come in that pack, there is one you can download around here somewhere, or you can just buy a deep drawer front. i have some extras at home (i think), but am on the road so can't be sure. i could mail one to you if none of the other options work well enough for you
i used a 24x24 pullout with a shallow drawer above it, always another option
