Here I go, having to get replacement glass for this skylight YET AGAIN. I installed the Andersens 5 years ago thinking that a respected brand name like that would be available for decades. Nope. They discontinued selling skylights the next year and I missed the memo from Home Depot. Fortunately they do have a parts department. Sadly, they want everything to be a difficult as possible and want measurements despite the fact that I have the part number of both the skylight and sash.
The skylights that I originally bought were SKS 2438 and 2446.
A pdf of the replacement parts catalog is here:

That's right, I have to read the google doc because Andersen pulled it from here: www.andersenwindows.com/homeowner/pdfs/Skylight.pdf
It can also be found here:

The part number for my replacement sash is 1880404
They don't have a way to buy it online, of course, but they apparently still do staff their parts phone center at 877-835-9090
