Key Features

• Complete package: Eight solid copper pyramid post caps are supplied with matching screws so multiple posts can be finished at once without sourcing extra fasteners.
• Designed fit: The caps fit about 3.5 x 3.5 in square posts with outer dimensions near 3.66 x 3.66 in and a height of about 1.26 in, offering a snug, finished appearance.
• Solid copper material: Crafted from solid copper for UV and heat resistance and long life, these caps will not corrode and will develop a natural patina over time.
• Simple installation: Each cap includes screws and requires predrilled holes for secure attachment, with the option to use adhesive like silicone if preferred.
• Low maintenance: The copper will last a lifetime with no maintenance unless you choose to preserve the polished look using a clear lacquer outdoor spray.

Who It's For

These post caps are best for homeowners, deck builders, and fence installers who work with roughly 3.5 x 3.5 in square posts and want a premium, longlasting cover that improves curb appeal and protects post ends from moisture.

Those who need exact factory tolerances or a different finish should check measurements before ordering; the caps are sized for about 3.5 in posts and have outer dimensions of about 3.66 in. Customers seeking stainless steel or painted caps rather than natural copper patina may want a different product.
