This set includes 2 universal cast iron gas stove wok rings, perfect for your kitchen, coffee makers, ovens, and gas stoves. Durable Material: The gas stove wok ring is made of high-quality iron with galvanization, making it flame-retardant, high-temperature resistant, odorless, and reusable for a long time. Safe and Practical: The non-slip wok gas ring features four convex corners for easy installation and removal. This design allows the wok to be fixed and makes it more stable during cooking, preventing the pan from tipping. Improved Energy Efficiency: The gas hob stand can adjust the distance between the gas stove and the bottom of the pan, allowing it to evenly absorb and distribute heat, improving energy efficiency. Strong Functionality: The cast iron wok ring is durable and not easily bent or deformed, strong enough to support the weight of everyday cookware, and offers a balance of anti-rust and non-slip properties. Compatibility: Works with most gas stoves to reduce the size of the gas ring, ensuring your moka pot, saucepan, or wok fits snugly over the gas ring. Size: 14*14cm
