Ordered two of these panels from Amazon expecting to receive panels with the clamp positions as shown in the images, dividing the panel roughly in half vertically (12" above the desk, 12" below) so it'd do double duty as a modesty panel as well as a desk divider.

The two panels we received have the clamp mount holes drilled at ~6" from the edge of the panel, putting 18" above and 6" below.

So: not as pictured.

The assembly instructions, on the other hand, show the mounting holes exactly as received.
The instructions make no sense, though, since they seem to indicate that the mounting holes go clear through the panel (they don't) and create some major confusion.
