Wall-Mounted Extendable Projector Stand

I purchased this item, opened it, and attempted to assemble it. However, I discovered it was incompatible with the projector I currently own and am therefore selling it without ever having used it.

It is in like-new condition, but please refrain from purchasing if you are concerned about this.
