Product review (5 stars): Works for Whirlpool Duet Models 9400
Used these for Whirlpool Duet Washer/Dryer Model #'s WFW9400SW00/WCD9400SW0.  Brackets connect above dryer to below washer so you don't have to worry about the dryer moving or falling off during an earthquake.  Good instructions.  Was able to open up more garage space for a workbench.
