Each 48 inch Channel Section includes a Joint Cap and 2 Push-in Fasteners.
Add these complete sections end-to-end at the bottom of your fence.
Calculate what you need by dividing the total linear feet of your fence by 4 and order that number of Sections.  Round up any fraction on the total by one section.
Example:  102 feet of fence to apply FenzSkirt >divided by 4 = 25.5  >>> You'll need 26 sections.
