Recently when a customer approached us with an historic door from New Jersey, we were excited at the challenge presented: create a replica of this unique design, to custom dimensions. We’re unsure of the precise history for this uncommon design, but this frame-and-panel door features a top paned window and a special sliding panel. The sliding panel is stored flush against the lower exterior of the door. When the threat of stormy weather, or other danger, arises, the resident can raise the sliding panel and lock it into place, covering the fragile glass panes.
