Product review (1 stars): A RUBBER BAND AND SCOTCH TAPE WOULD BE MORE EFFECTIVE
If any other clamp is available, try it before buying this under-engineered piece of junk.  The clamp is made JUST big enough to fit around the vent tube, IF that tube were perfectly smooth which, of course, it's not.  You need to unscrew the clamp until the screw is on its very last thread to make it fit...and even then, it's a major accomplishment to get it on.  Whirlpool must have saved a penny in materials on every 10,000 of these things by making them 1/8" too short.  A little job that should have taken less than five minutes turned into a half hour of cursing.  Having said that, Whirlpool's vent tube is pretty nice, as it's thicker than most.  It didn't crumple like cheaper ones do when you apply pressure on its walls when stretching it out, or while bending it into place.  So, buy the tube; forget the thin, short hunk of scrap metal they call a clamp.
