The ergo spout fits all standard-size 2.75"-inch mouth mason jars regardless of size (e.g., half gallon, quart, pint). It is compatible with most mason jar brands including Ball, Kerr, Kilner, Atlas, and Golden Harvest.
Promising review: "I recently took my ergo spout on a family reunion trip. I had mason jars filled with special salad dressing and maple syrup from a bulk gallon, enough to feed my family group of 17. It was so convenient to transport the condiments in sealed jars, then screw on the ergo spout to serve them. The salad dressing was easy to pour on everyone's Cafe Rio–type salads, and my sisters all commented on how beautiful and convenient it was. The next morning, I was able to put the jar of syrup into the microwave to warm it up, then screw on the Ergo Spout to help pour the syrup as well. No need to transfer the syrup more than once. Plus it looked so classy. I was very proud to have this beautiful tool to take with me." —Liz
