Product Description

This is an Aluminum Two Dog Nautical Porthole – 21″ (Off-Balanced Inset). What we mean by off-balanced inset is that, instead of the porthole sitting 0.75″ deep for all 360 degrees, about 40% of the inset is 1.5″ deep. When this was installed on a ship, it was custom-made to fit the wall it was being put in. This is both unique and allows for a sturdier installation.

Both of the closure dogs spin on and off with no problem.  Some customers have used a porthole-like this to make a medicine cabinet in their bathroom. The handy thing about these aluminum portholes is that they weigh less than their brass counterparts — allowing you some more flexibility with methods of mounting them!

There will be a slight marking on the glass of this porthole window because it is an authentic salvaged nautical item – you may choose to have a mirror added to this if you dislike the visible salvaged history on the product.

If you are looking for a unique piece of glass to use in a door or a bathroom this item is for you!

The word “porthole” has nothing to with its location on the port side of a ship, but originated thanks to Henry VII of England in 1485. The king demanded mounting guns that were too large for his ships and French shipbuilder, James Baker was brought on to solve the problem. He pierced the ship’s side so that the cannon can could be mounted inside. When there was heavy weather or the cannons were not in use, the openings in the ships were fitted with covers that latched tightly. These were called Porte, which means door in French. Porte became port thanks to the English and eventually, any opening on a ship was called a porthole.
