Picture of a Canterbury-style vinyl fence.
Vinyl Fences are a popular alternative to wooden fencing, because they are low-maintenance. Vinyl fences come in many styles; in the fence picture above, the Canterbury style is used. I see Canterbury vinyl fences as essentially a two-tiered style, consisting of a top tier of balusters with normal spacing and a lower tier spaced more tightly.
In the next landscaping photo, you'll see a different example of a baluster fence....
