Sturdy heavy duty, chromed steel in a tight .5"/1.27cm wire grid provides optimum support and prevents baked goods from slipping through the rack. Tall 1"/2.54cm legs ensure better air circulation and faster cooling time. High heat resistant up to 600°F/315°C. Legs will rest inside 19" x 13" baking sheet to use as a baking rack inside the oven. Use as a trivet for hot baking sheets and casseroles and protect your counter tops and tables.
