I need a large outside caliper and can't seem to find one. My friend has one that measures 25" when fully open and 26" top to bottom. He can't remember where he bought it. Any suggestions? Thanks.

I think his is an 18"
I can't tell from the description if 18" throat means the distance between the points or width in the middle.
It would be easy to make your own from 1/4" plywood or Masonite. A 1/4-20 bolt and wingnut will lock it in position.
Harbor Freight - It's made of Aluminum and costs less than 10 bucks.
I checked the online catalog and it isn't listed. The Caliper is 24" with jaws that are about 3+" deep and has a vernier scale. It has no part number, just "Made in China" as its only markings
I found it in the store and your local store may have it too. The stores and catalog don't always match.
