Brand new Arctic Tern 450x1100 window. We bought this window for our box truck RV conversion but decided we needed a different size and shape window, and unfortunately it was too late for a return. This window has never been installed or even opened. It has all components and has the protective plastic coverings still on the window. See ternoverland.com/450x1100mm-arctic-tern-window/ for information from the manufacturer.
