My escutchen came with two foam gaskets, pre-installed. One seals the center hole, the other seals the outer diameter.
So, we have 2 different answers here. Some users say it is 1 13/16 (1.8)" and others say it is 2.52 (directly from Delta). So which is it? And if it is indeed 2.5" - then what is the part number for this same escutcheon in 1 13/16 (1.8)" ? Thanks in Advance, DD
