This fireplace screen fit our opening perfectly. Assembled very easily. We like that it sits flush against the front of the fireplace and also against the floor, as our gas logs have small pieces of gravel around them and this keeps our little ones from getting to those. We assembled with the middle support bar facing the same direction as the legs, which really helped make it even more stable (read even more difficult for kids to pull down). They havent messed with it...success!
