Inviting in appearance yet preserving a sense of security, Closed Picket vinyl fencing is popular with homeowners nationwide. The gap between pickets allows visibility and airflow but are still spaced close enough apart to help prevent children and larger pets from wandering off. If you want the classic yard perimeter, white picket fencing is a must! Closed Picket fencing is distinguished by the horizontal bars that completely enclose the vertical pickets like a grate. America’s Fence Store sells vinyl picket fence panels in heights ranging 4-5 feet.
