Hi I'm Al Martins, we're going to talk about the difference between the Pro Series and our standard series of Fence Armor. They're exactly the same material they're exactly the same strength, the difference is the height. So our Pro Series is six inches high and our standard series is three inches high so depending on if you have an existing post and there’s a lot of damage on it already and you want to cover it because it's just going to look better, that curb appeal is going to go up. Or your landscaper is just up and down that post and doesn't know where the ground line is then you want to go with the Pro Series, again comes in two halves but it is six inches high. Our standard series is three inches high and also comes in two halves.
