3 pcs wok ring: 2 pcs size A and 1 pc size B. This wok ring features non-sharp edges on both ends and is ideal for use with round-bottom woks. Universal fit for gas stoves and fry pans. For round-bottom woks, select a wok ring with an outer diameter smaller than the wok’s base diameter. Durable construction with perforated sides and a flat, stable rim. Designed to support woks when cooking on standard stovetops. Place the ring with the narrower side down for use on small electric burners. Efficient heat transfer—heat rises and cools quickly, mimicking gas burner performance. Fully covers heating coils to maximize energy efficiency. Ring fits precisely around coil elements. Flat-bottom woks sit close to the heat source for optimal heat absorption. Small gap between wok and coil allows even heat distribution and prevents burning. Minimal spacing reduces movement; flat-bottom woks and flat coils maintain stability. Features grooves on the bottom to prevent sliding. Compatible with stove grates that have four prongs arranged at 90-degree intervals. Stable fit for round-bottom and flat-bottom cookware, including woks and pots (minimum bottom diameter: 3.94 inches / 10 cm). Also suitable for round-bottom woks on gas stoves with standard grates. Provides secure wok stabilization during cooking. Includes 4 notches for easy attachment to stove tops.
