These protective coverings, typically constructed from durable materials like metal, plastic, or wood, fit atop fence posts to shield them from weather-related damage. A spherical top is a common design choice for aesthetic appeal and effective water runoff.
Preserving the structural integrity of fence posts is paramount for the longevity and stability of any fence. By preventing water absorption and subsequent rot, decay, or cracking caused by freeze-thaw cycles, these simple components contribute significantly to a fence’s lifespan. Historically, simpler versions, often made of wood or stone, served a similar purpose, demonstrating a long-standing recognition of the need for post protection.
