12" Cast Aluminum, with Nickel finish, Port Hole Window and Inner Channel Flange.
This style is particularly suitable as working windows in many structures, as you can have a finished look on both sides.
Opens from front side, with typical porthole latching hardware that is of high quality. The backside also made of solid same nickel finish.
The frame and glass sustains outdoor rain and cold winter weather conditions.
Bonus: Also there is another glass on the backside. Both pieces of glass are removable (secured by screws) if you desired for customizing. For instance one customer removed the glass to use this porthole as a pet door.
As a retailer, we do not perform any installations.
Very well built and packaged to arrive safely.
Porthole overall Dia: 12"
Window Dia. (front and back): 7-5/8"
Tunnel Depth: Threaded hardware included for depth of 1- 5/8" with fully finished nickle channel flange. You can also find custom fastener lengths to use for thicker applications.
Porthole can adjust to multiple sized walls and doors. Channel flange is welded to front portion of porthole and extends 1-5/8" towards back plate. If you have a thinner wall, or door, 1) just shim one or both sides when installing or 2) cut and grind channel flange to shallower depth.
If you need the depth to be more than 1-5/8", just swap out the bolts (your local hardware store) for similar, longer ones. You may want to fashion a deeper channel to give a finished look.
Also comes complete with a nice thick gasket to keep weather out.
