Match Your Surroundings with  Our Ready to Finish Kits These gas fire pit enclosures are unfinished to allow you to finish with stone, veneer, or stucco to match your surroundings. Shapes are available in round, octagon, square, and linear. The housings take the guesswork out of enclosure construction, especially with the difficult round and octagon shapes. These are 18” tall and are constructed of sturdy 22 gauge galvanized steel material, welded frame, a 1/2” Hardiboard shell, and weighs 150lbs. The enclosure does not include the burner system. This enclosure kit can be used with a 36″ or 48″ trough or 30″ or 36″ H-Burner system.
