We offer metal finial caps in the following sizes, 2x2, 2.5x2.5 and 3x3. These finials are perfect replacements for ornamental fencing that has lost it's manufacturer provided caps. Replacing finial caps is important for the longevity of your fence. They protect the inside of the fence from prematurely rusting, and ours come with a durable powder coating that will last as long as the fence itself. These aluminum finial caps are "slip-over" style and can be used with any matching size post. These caps are designed to be a friction fit or can permanently attached via epoxy or welding.
