The Liberty Foundry 20 in. Heavy-Duty Cast Iron Fireplace Grate with 4 in. Clearance is constructed of heavy-duty cast iron which stands up to the hottest of fires. By comparison, imitation cast iron grates minimize the weight of the iron where it's needed most, delivering a counterfeit-casting that buckles under heat. This cast iron fireplace grate is designed with long-term durability in mind, equipping you with long-term performance. You'll feel the difference of a Liberty Foundry fireplace grate right out of the box! Cast as a one piece, heavy-duty, flat bottom basket-style fireplace grate, the G800-20-BX model measures 20 in. (front) x 16 in. (back) x 15 in. (depth) with a 4 in. cast-on leg clearance. Durably built, each grate weighs approximately 23 lb. (Actual forged grate dimensions and weight may vary slightly.)
