Due to the hinged nature of the screen, the diameter is shorter one way than the other, which allows the shorter screen to easily rotate open inside the larger half of the screen. Hinged spark screen allows easy access to the fire without the need to remove the screen and has convenient handle on top to lift the screen on and off. Spark Screen Lifter included. Please measure your fire pit to confirm a 24-26 inch screen will fit securely. Intricately woven mesh made of polished Stainless Steel. Stainless steel is weather resistant for added longevity. Prevents sparks and embers from escaping.
