More to the point what is reflected in this huge mirror I almost always just lean these on the walll in a vertical position as most of the time what they reflect is not worth seeing twice so when leaned I can choose the reflection I want.

l would use Hercules Hooks, they support 150pounds and are extremely easy to use, Amazon.com has them!

A) There is a (5'W) sideboard on the same (N) wall (which will be below the mirror).

B) This is the only available wall in the DR. The DR entry(S) is to the left or north of the front entry hall.

C) The DR ceiling is 12'H. The (N) wall that the sideboard & mirror would be on is 11-12'wide.

D) The two other walls(W and E):

W) wall is large windows on the front of the house. NOTE: The window side has plantation shutters to control light/or reflective issues when needed.

E) wall opposite the window wall is an opening to the kitchen/FR/Breakfast area.

Thank you for your quick reply.
