A real improvement over conventional steel racks, our canning rack is entirely made of tough, flexible silicone, so it will never rust or warp. It also cushions well, so jars won't rattle against the bottom as they boil or break if they tip over, and the closer spacing of the 1/2" mesh helps keep jars from tilting.
The rack can also be rolled up so it’s easier to store. Forming a snug fit in standard 12" diameter canners, it withstands temperatures up to 400°F (200°C). Highly recommended.
