Rotating duplicate issue

When I rotate my duplicates they end up higher on the z axis . I put the 3d cursor in the right place but the planks are higher than they should be.

    Can you post a screenshot of what you're seeing? Additionally if you provide a download link to your .blend file then I can take a closer look at what's happening. (The best way to provide a download link is with Dropbox, Google Drive, or equivalent file hosting service)
