Product review (3 stars): needed some extra work.  better fr #10 screw bracket than #8
the cams for the upper and lower part seem to be a different material....the lower feels denser.  the fit was fine in my 19 year old side by side refrig.  the problem was that the better screws that secure the lower half to the bracket were too big to fit in my bracket, and the ones supplied that were my size did not have this little offset section to keep the cam from sliding back and forth when the refrig was opened all the way.  in other words, the diameter of the hole for the screw in the cam was too large for the screw(without the offset) for my bracket.  in the end, I had to enlarge this hole to 3/8 and put a washer in there to act as a spacer and a bigger washer on top of that.  after this, worked perfectly. maybe it is the age of this refrigerator..in other words, the #10 screws with the offset, if this fits the bracket, works far better than the #8 ones.  according to the instructions, it could be either. I guess the #10, which works the best, looks like a shoulder bolt with a very narrow shoulder.  The #8 has no shoulder, thus, allowing for the slippage.
