Nominal 11x11 Copper Fence Post Caps

Heavy-Duty Copper Caps for Large Wood Fence Posts

Protect and finish large fence, gate, deck, and railing posts with our Nominal 11x11 copper fence post caps. Made from thick, real copper with a seamless pyramid design, these caps help shield exposed wood from rain, snow, and moisture that can lead to splitting, cracking, and internal rot over time.

These copper caps have an inside dimension of 10-5/8 inches and are designed to fit posts measuring up to 10-1/2 inches. Since lumber sizes can vary, we strongly recommend measuring your posts before ordering. The angled pyramid shape helps direct water away from the top of the post, while the seamless one-piece copper construction creates a durable, leak-resistant barrier.

• Inside dimension: 10-5/8"
• Designed to fit posts up to 10-1/2"
• Made from thick real copper
• Seamless one-piece pyramid design
• Includes matching copper nails (2 per cap)
• 3/4" side depth

Over time, the copper naturally develops a rich patina that may range from antique penny brown to verdigris green depending on climate and environmental conditions. This aging process is normal and can take many years.
