I just purchased a $20K Kraftmaid kitchen from Lowe's. The Lowe's Kraftmaid demo shows interlock construction on the pantry slide-outs and all-metal construction.
Same all-metal constuction construction with the interlock design slide out drawers. Here is what was delivered for pantry slide-outs: cheap non-interlock construction drawers (stapled) with plastic mounting hardware that has already broken. Here is what was delivered for drawers: interlock construction BUT...plastic back mounting hardware that already shifts 1/4". Add a few years of plastic fatigue and this $20K investment is toast!
I am very pissed off at Lowes for the "bait & switch" demo. I am insisting on a complete rework of pantry and drawer hardware or this *** is gone!
