Product review (1 stars): Does not do the trick...
I ordered this item for a Whirlpool washer that was purchased as an open box item that did not come with a drain hose.  This item, as described by other reviewers in a different area about this very product, is not sufficient to complete the job.

a hose and 1 clamp is what is all that is included.

No interface to the washer drain is included so there is no way to connect to the back of the washer.

No adapter is included either, so this cannot be used as an extension if 4 ft is not long enough. you will need the adapter from whirlpool.

Also not included is the "U" shaped end that allows the hose to be properly secured into the drain.

If you think you can walk into a Home Depot or Lowe's and purchase any of the lacking items needed to complete the job save your time.  No one carries anything that is compatible with this item.

I purchased a generic kit from Home Depot for $9 (American Standard brand?) that included everything.  The only modification required was to cut the rubber drain connector shorter so that it would snugly fit around the 1 in diamter drain.  The drain has been installed for over a month and is working without issue.

I'm not sure what this item is intended to fix, but it is very likely that it will be nothing more than a waste of time and money for you.
