Dedra R Wichita , KS March 08, 2016 I needed a stack kit for an older whirlpool duet pair I ordered a stack kit according to the model numbers on the washer and dryer and the kit worked perfectly. My washer and dryer are now stacked and I am extremely satisfied with how easy it was to order from this website and the quick delivery of my part. Thank you! 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
