Circular caps designed to protect the tops of fence posts from weather damage are available in a 100mm diameter size. These protective covers shield the vulnerable end grain of the post from rain, snow, and sun, preventing rot and extending the lifespan of the fence. They are typically constructed from weather-resistant materials like metal or plastic.
Preserving fence posts represents a significant cost saving over time. By preventing water ingress, these caps mitigate decay, reducing the need for frequent replacements and contributing to the overall structural integrity of the fence. Historically, various methods have been employed to protect post tops, ranging from simple metal coverings to more elaborate designs. The widespread adoption of standardized sizes, such as the 100mm variant, simplifies installation and ensures a proper fit.
