Michigan Ladder Company makes ladders in Ypsilanti.
I just emailed with Louisville customer service, about these specific model numbers:
AE1232HD - 32' aluminum extension, 375lb capacity
AE2232 - 32' aluminum extension, 300lb capacity
AE2832 - 32' aluminum extension, 300lb capacity
Those meet the OP's requirement. They're made in Mexico.
Further, depending on the model of ladder, others are made in the USA, Mexico or China.
Isn’t Werner made here?
Well, according to this product listing on eBay:
https://www.ebay.com/p/Werner-D1532...Flat-D-Rung-Extension-Ladder-32-ft/2254531204
The D1532-2 (32-foot, aluminum, 300lb load) is made in the US. However, I can't find that information on Werner's product page for that model, nor is it displayed on Amazon, Home Depot, Platt Electric or Zoro's product page for the same model.
I have been trying that. Werner and Little Giant are no gos. China and Mexico respectively.
Racist much? What is it with GJ these days?Well. The parent company is probably owned by 3 dudes from China and 2 from Taiwan and the bean counter is probably a Vietnamese chick.
The guys who glue them together in ol'#1 are probably a couple wops.A guy from Iceland, 3 rednecks and a kid from El Salvador.
Now.Are the ladders nice ? Price OK ?
Guarantee ? Buy the thing.

Not familiar with racial slurs for Italian Americans, are you? Glad to see the mods removed the offensive post.His post had zero mention of any particular race. What the **** are you talking about? Lets talk about ladders, please.
Wing (Little Giant) makes their higher end ladders in Utah. Smaller ladders are imported.
Green Bull ladders were bought by Werner in 2008, but they claim that a majority of their products are still made in the USA. Louisville, Kentucky to be exact.
