Product review (1 stars): Broke aftet a month of use.
These are very poor quality. Mine broke after a month of use. Look elsewhere for a better product. I should of contacted manufacturer and bought a certified replacement. Also when I took it apart other pieces started falling off. I was delicate in removing parts as it's a pain to find replacement parts.

Also be weary this seller will make you pay for return shipping AND deduct the price of original shipment from your return as well as a potential 20% restock fee.

Edit: If you're looking to replace these I suggest seeing if this will work with your dishwasher (I replaced this poorly design rack adjuster with the following and it's just a far better design that will last a lot longer): https://www.amazon.com/gp/product/B00SPYDSFC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

For those weary of links just search on Amazon for Whirlpool W10712394 Adjuster KIT.
