Corbel is not square
I've ordered many of these, every shipment is the same. Corbels installed are measured at top and bottom shows they are leaning to the left by 3/16". When facing them they slant from top left to bottom right. So we have to push bottom to left and grind the top left to keep them square with our columns.
I am pleased with my purchase and the quick delivery of my order. The detail of the corbels is very good, although the features are not quite as soft as the image posted is in real life. I am somewhat tempted to try a little sanding to round out the grapes and leaf features.
