Beware. Buy more stakes if you get this. Install this in two stages or it will look bad. Stake the two farthest points in a straight line on the hottest day you can find, then wait. The heat makes this thing super bendy and defeats the purpose of the product. The more stakes you put in before the heat stretches it, the more you have to pull out and redo to make it look right. I know heat expansion is simple physical chemistry, (adiabatic expansion anyone...no?) but it makes this look like trash.
