Robinet de cuisine à deux poignées avec accessoires LKD2432BHC

It didn't work on a stainless drop in sink. All three columns are fixed to each other under the sink and I couldn't tighten down the center piece enough to close the gap. Can't explain the whole picture with words. I put a wall eschuteon under the middle trim piece to fill the gap and crossed my fingers. I am an experienced plumber, also two other skilled plumbers were scratching their head over it too. Other than that, water did glow thru it and the hot and cold side worked like it should. Would not order again.
