These all metal fence kits can 1) have no overlap or 2) have overlap. Overlap is additional fence on the ground that covers changes in grade. This overlap is important if A) you have sloping or irregular terrain or B) if you are trying to keep animals in or out
The kits below that have overlap start with the letter "o" in the title.
Notes on size and length: The two numbers in the item name are height and length. For example, 8 x 300 is 8 feet tall by 300 feet long. If you have a project with 600 linear feet, you would need two 8 x 300 fence kits and so on.
