End Post or 1 Way Post for a PVC fence is a type of post that is installed at the end of a fence line, where the fence stops. It is a sturdy and durable post made of PVC (polyvinyl chloride) material, which is known for its resistance to weather, moisture, and insects. The End Post serves as an anchor for the fence and provides support to ensure the fence remains upright and secure. It may also have holes or slots to allow for the attachment of fence rails or panels. Overall, an End Post is an essential component for any PVC fence installation to ensure a strong and reliable fence system.
