Measure the diameter of your firepit. Replacement firepit screens come in a variety of standard sizes, including 22 inches, 25 inches, 29 inches, 33 inches and 40 inches. You also can order a custom screen, if you cannot find a standard screen that fits your firepit.
Select a screen made of safe material, such as stainless steel or iron. Iron screens probably will be cheaper and heavier than stainless-steel versions. The iron screens are covered with heat-resistant paint to protect them from the elements.
Choose the style of your screen. Firepit screens can be domed-shaped with swinging doors or embellished with handcrafted designs. You also can find screens to fit square firepits.
Visit websites that allow you to comparison shop. At these sites, you can compare prices and read product reviews for a variety of screens, which will help you find the right replacement firepit screen at the right price.
