This 12" round porthole window is for camper van builds where a full-size window won't fit. When cabinets or a bed take up most of the wall, it adds light and a view without taking over the panel space you've already planned.
This window installs into an 11-11/16-inch cut-out and has a 12-7/8-inch outer diameter. The smaller circular opening adds daylight and a view outside without requiring a large rectangular cut in the wall.
The black powder-coated aluminum frame surrounds the glass and holds it in place. Aluminum resists corrosion, so the frame will not rust over time.
This bunk window sits at eye level from outside, creating a direct view into the sleeping area when parked near others or in public spaces. The 17% gray tint limits how much someone can see inside while still allowing visibility out. It also blocks 83% of UV rays, reducing sun exposure through that section of glass.
The clamp ring sandwiches the van wall between the interior and exterior frame to secure the window. The reversible ring allows installation on either side and forms a weathertight seal when used with foam seal tape so you can add light without giving up usable wall space.
