Product review (1 stars): Not a good choice for side-mounting on particular models!
So I bought this part for an LG LDF7551ST (in same family as:  LDF8574ST, LDF8072ST, LDF7561ST, LSDF9962ST).

My situation is that the dishwasher is placed under a granite counter.
The installer had mounted the dishwasher on the sides to the wooden cabinets.
The mountpoints on the dishwasher were made out of the sheet metal on the sides.
So eventually these fatigue (installer didn't level the unit properly and installed it very low).
That probably added to the fatigue, but hey eventually they will fatigue.

So I bought these pieces hoping I could use them in lieue of the factory "built-in" pieces.
BUT they really don't fit per se, since the manufacturer didn't provide a little slit in the metal
so as to hold it in.  If they did the job would have been 5 minutes.  However I had to shape
these pieces into something that would fit, and at that not too well.  I just finished putting it all back together.

I could have just as easily bought some metal and shaped into pieces.

I just wish LG would have put the slits up higher so these clips could work.  But the engineering on the side
mounting of this dishwasher was very short-sighted.  Rather than have premade brackets in the metal,
they should have just used the brackets to begin with.  Would really help!

Don't waste your money on these.
