Anyone interested in one of link these? they're still in packaging, never used. i have 2 available. $40 delivered in the US. should fit into a large flat rate.. possibly a medium.

Boy I thought these would blow someone's skirt up.

Pretty limited use if they are the 0-1" range you linked to.

Pardon my ignorance but what are they used for?

I used a 0-1" Dwyer for draft on my stoked stove. sure you're using the bottom end for .02-.05. I paid $110 for mine from the local fireplace center

Stack pressure in a combustion stack for instance.

I use a 0-5" magnehelic to monitor the filter in my dust collector. When the pressure gets to 3" I know it's time to clean it.

Same here, I also have a 2" one I use with a pitot tube to calculate air flow in the DC ducting.
