Dual Cam Earth Wire Gripper Industrial Grade Clamp For Overhead Ground Wire Work​

Core Design Features​​

• ​​Dual-cam locking mechanism​​ with 180° opposed cam profiles for balanced force distribution
• ​​Aerospace-grade aluminum alloy​​ (7075-T6) main body with stainless steel cam components
• ​​Self-adjusting jaw pressure​​ adapts to 8-16mm diameter earth wires (including OPGW 12-48 fibers)
• ​​Working Load Limit (WLL):​​ 10-50kN (color-coded by capacity)
• ​​Non-marring nylon jaw inserts​​ prevent damage to wire coatings
• ​​Integrated load indicator​​ shows real-time clamping force

​​Operational Advantages​​
✔ ​​40% faster installation​​ vs traditional screw-type clamps
