String Line
Definition
A string line is pulled tight between the two end or corner posts of a fence run before any line posts are driven or set. Each intermediate post is then positioned so it touches the string without deflecting it, ensuring all posts fall on the same plane. String lines are also used to establish consistent post height — though Thrive cuts post tops level after panels are set rather than pre-measuring each post. A fence installed without a string line will show a slight wave in long runs, even with experienced installers.
