What is the maximum distance between the 2 rulers?

I don't have mine here but I'd estimate 2 to 2-1/2". It really doesn't matter since you can walk the parallel ruler across the chart to a compass rose or wherever. Check the Power Squadron video at https://www.youtube.com/watch?v=xKSBYfscA80.

What shape is the product in (the packaging was damaged...is the ruler damaged?)

Are you getting? That is a plotting device aka parallel plotter or ruler, http://www.weems-plath.com/store/product-list.php?id=20566for Weems and Plath.Good Luck

What shape is the product in (the packaging was damaged...is the ruler damaged?)

Mine was in perfect condition and about a year later it still works great. Just send it back.

Great size, and quality. Has both metric and imperial measurements, which I deem essential.

Previous versions of this W&P divider had more heft and felt better in hand because it had smooth curves. This edition has more hard angles and just doesn’t feel as comfortable. Although it’s all metal still, the top design feels cheaper in hand. I’ll keep this as a backup, but am going to look for an older used one instead.

Excellent set! Having the slightly larger parallels is well worth it. Replaced my 12” with this 15” and will never look back. Excellent quality, easy to use and durable.
