Overview

A four-burner propane grill from Thermora with 645 square inches of cast iron and stainless steel cooking area, built on a freestanding black frame.

At 22.1 x 46.1 x 56.5 inches, it's narrower but taller than some comparable four-burner grills, which may affect where it fits against a wall or railing. Cast iron grates combined with a stainless steel body follow the same durability pattern common across this category.
