I've used a bamboo steamer for a couple of years, which is not ideal, and is now falling apart
The guys at The Bitten Word crafted a really clever barrier for their Tomato Canning marathon:
Clever, huh? What do you use?
LOL, Pat! You are thinking too hard. I usually have the water warming as I pack the jars, then set them in the water. When the canner is full, I bring them to a boil together, and time them. As long as they all have the full time, and you don't leave them in too long, they are all good. I don't use the rack because lifting a rack of full jars is not the easy way to do it. Work smart, not hard. LOL, that is a common saying in my trade, but it applies to all of life.
When I buy cheap trash bags with wire ties, I keep them. Those ties work great for putting some rings together.

Like Sparky, In my pressure canner I just sit the jars inside on the spacer that holds them off the bottom and use the jar tongs to remove them. I haven't had any issues with jar breakage. I do use a wire basket in some of my waterbath canners but it's used primarily to allow me to lower all the jars at the same time into the boiling water instead of trying to remember which one went in first and should come out first.
I sometimes do double batches in the same boiling water and if I use the basket I can Hot pack the second batch and put them in the basket to be lowered into the boiling water at the same time. I was trying to cut time by getting the water boiling in the canner at the same time I was heating/cooking the product to be hot packed.
