Product review (5 stars): Fits my Whirldpool WFW9150WW01
Installation is easy, and if in doubt look for a YouTube video "Duet Washer Door Strike (part #WP8181651) - How To Replace".  The only tough part is to find a Torx 20 screwdriver (star bit).

It looks exactly like the original, which isn't all that tough in the first place, because mine broke, leaking water everywhere.
