Product review (1 stars): strain relief clamp designed by an id! ot
The strain clamp comes with two independent clamp pieces that are joined by two screws in each sides' ears that have pre-drilled holes in them.  The hoes are not pre-tapped to accept the screws, but what you get are self-tapping screws.  However, it is *impossible* to use the self-tapping screws to tap the opposing holes because the amount of force required is much more than you can both deliver by hand (or at least with my rechargeable power drill) and that wouldn't strip the screw head.  If you get this item, prepare to get your own threaded screw and locknut because the ones that it ships with are unusable, so expect to make an yet another trip to the local hardware store.

The ears that provide the strain relief are also oriented perpenticularly between how they need to finally be mounted versus the attack angle you need to access it during assembly (driving the screws for clamp-down) -- at least for my GE dryer.

The insult is that this is the most expensive product in its class $24 at HomeDepot.  The quality of the rest of the assembly is otherwise fine, but otherwise impossible to install correctly as delivered.
