Durable material: The gas stove wok ring is made of high quality plated iron wire, which is flame retardant, high temperature resistant, odorless and can be reused for a long time. Safe and convenient: The non-slip wok air ring has four convex corners, easy to install and remove. This structure secures the wok making it more stable during cooking and avoids turning the pan over. Higher energy efficiency: the gas hob can adjust the distance between the gas hob and the bottom of the pan, so that it can absorb and distribute heat evenly and improve energy efficiency. Strong features: cast iron pan ring is durable, not easy to bend and warp, strong enough to support the weight of everyday kitchen items, and has a balance of anti-rust and non-slip properties. COMPATIBILITY: Compatible with most gas hobs, reduces the size of the gas ring, allowing pots, pans or moka woks to fit perfectly on the gas ring.
