- Material and build: Cooling racks are made of pure stainless steel. No toxic materials leaching into food and no aluminum coatings to fail. Solid construction with a thick outer frame and 3 cross bars provides great load-bearing and absolute stability. Rust- and warp-resistant for long-lasting daily use. - Size and performance: Each rack measures 15.3" x 11.25" to fit inside a 16" x 12" baking pan. The 1/2" x 1/2" grid spacing keeps food from falling through. 0.75" raised feet lift the rack for optimal air circulation on all sides, promoting even baking and faster cooling. - Easy to clean: Wires are finished with a mirror-like polish to reduce sticking. Easy to clean by hand with soapy water, a sponge, and a quick wipe of the cross sections. Dishwasher safe for time savings. For tough scraps, soak briefly and use a vegetable brush. - Oven safe and uses: Heat-resistant up to 575°F and designed not to release harmful substances at high temperature. Suitable for baking cookies, croissants, bacon; roasting chicken or vegetables. Works with pans to drain fat and grease for a crispy crust on chicken, bread, and fish.
