21″ Aluminum Porthole Window with Square Dogs – Flat Back Mount

This 21-inch aluminum porthole window is an authentic salvaged ship piece that brings a clean, functional look with real maritime history. Its lighter aluminum frame makes it easier to mount than heavier brass portholes, while still keeping the rugged feel of original ship hardware.

The glass is in good condition with only a few minor scratches from use at sea. The window opens on its hinge, and three square dogs secure it when closed. This square dog design gives it a more industrial look than standard round styles. The back has no inset, so it sits completely flat against the wall for a clean and simple installation.

You can use this as a wall feature, a working window, or convert it into a mirror. A mirror option is available through the dropdown for an additional cost. If selected, we will have the mirror custom cut and installed before shipping, which will extend the handling time.

Key Features:

• 21-inch aluminum porthole with lightweight construction
• Three square dogs for secure closure and a distinct look
• Glass in good condition with light surface scratches
• Flat back design for flush mounting
• Optional mirror upgrade available

Only two available, and each one is a true salvaged piece.

Items without a mirror usually ship within 1–2 business days. Mirror orders require additional time for custom cutting and installation before shipment.
