A window is a cut-out in a full skirt, usually filled with clear vinyl. Windows are either rectangular, rounded rectangular or domed. A standard window is permanently sewn in but, can be ordered with zippers along the top and down both sides. Other options include interior roll-up covers, faux panes, solid Lexan and tinting.
Frame rafters can be wired internally for 110v or 220v receptacles. Pneumatic tubing can also be threaded through the rafters to deliver compressed air or other gasses.
