The CW-PA39 Tension Clamp is engineered for the secure fixation and tensioning of messenger wires in overhead cable installations. Designed to meet the rigorous requirements of the NFC 33-042 standard, this clamp provides a reliable and durable solution for maintaining line integrity under various environmental conditions.
Key Features
-
Body & Wedge: Constructed from high-grade, weather and UV-resistant thermoplastic. This material offers exceptional long-term stability, preventing cracking or degradation caused by sun exposure and extreme temperatures.
-
Bail (Hanger): Fabricated from hot-dip galvanized steel, delivering superior corrosion resistance and robust high tensile strength to withstand heavy mechanical stress.
