PVC caps for pole top

The low-density polyethylene (LDPE) caps are specifically designed to seal the upper end of light poles. They provide high mechanical resistance, ensuring long-lasting protection against weather exposure. Ideal for preventing the ingress of water and debris, these caps ensure the longevity and efficiency of light poles, contributing to minimal maintenance and a neat appearance.

CLOSURE CAPS IN PVC model TPVC121

 

The polyethylene caps, model TPVC121, produced by NCM, are specifically designed to seal the upper end of light poles. Featuring high mechanical strength, they provide long-lasting protection against exposure to weather elements. These caps are ideal for preventing the entry of water and debris, ensuring the longevity and efficiency of the light poles.

Thanks to their sturdiness, they help maintain a neat appearance and reduce the need for maintenance. They represent a practical and effective solution to protect the ends of poles and preserve their integrity over time.
