Product review (5 stars): Seems an original WP part
Service came to fix my KitchenAid dishwasher that was leaking and took off with one of these parts. Since the whole thing was a bit wobbly even with two pivot points, I figured I might as well buy 3 of these. One to replace the missing one and 2 for the middle on each side. The whatever-you-call-them are now pivoting on 3 points making it much more sturdy. They seemed identical to the original one and the packaging seemed legit for a WP item but who knows... Regardless they do the job.
