Product review (5 stars): Very Thick and Does the Trick
This is a nice, thick and heavy cord for newer 240V dryer outlets.  I wired this up to a Whirlpool Cabrio dryer, model WED5500XW0 and it went in without a hitch.  There was not really a place for the included strain relief clamp, so I clamped it in a place that would keep the cord away from the sheet metal.

The cable itself is very thick with what looks like 10 gauge wiring covered by a thick layer of rubber insulation.  It feels substantial in the hands.

Keep in mind that this cord will not work on 240V stoves.  The new 4-prong receptacles have a slightly different design between stoves and dryers.
