This square steel fire pit ring provides a defined outdoor boundary for a custom wood-burning fire pit area. With a 36-inch outside footprint, a 30-inch interior opening and a listed height of 10 inches, the insert is sized to coordinate with many square landscaping designs. Its stated 2 mm steel wall thickness distinguishes this model from the thinner 1.6 mm version. Four steel panels form the ring, and the original product listing includes the bolts, nuts and washers used to connect the sections. The separable design suits projects using compatible landscape pavers or masonry surrounds while keeping the visible fire pit profile clean and straightforward.
