Aluminum 1" Thick Fixture Plate 1/4-20 Threaded Hole Grid - $525 (El Cajon)

Up for sale I have a custom made 1" thick aluminum optical breadboard/fixture plate.
This is a single piece of aluminum, 1" thick, measuring 43" wide, 24" deep.
The plate has counter-sunk holes at all four corners to bolt it down to a bench or to a set of legs.
It has 1/4-20 tapped holes on 1" centers and is anodized black.
The grid of tapped holes spans an area measuring 37" by 18".
The holes extend all the way through the plate.
This is a seriously beefy fixture plate.
Total weight is exactly 100 pounds.
This came from an optical lab and was used inside of a vacuum atmosphere glovebox.
It has some small nicks and scratches over its surface from normal use but there are no major dents or scratches and of course it is not bent.
New price on this plate was many thousands of dollars.
A 24"x24" solid aluminum breadboard only 3/4" thick would cost you over $750 from Thorlabs.
This is twice as big and 30% thicker.
The 1" aluminum plate alone is over $1000 from most metals suppliers.
I'm selling this fixture plate/breadboard for $525 cash.
Located in El Cajon, a few blocks from Gillespie Field.
