Installation Tips for This Fitting
Before installing your clamp, ensure the wire ends are clean and free of rust or debris. Then, thread the wire ends through the clamp as directed. In addition, tighten firmly to prevent slippage under load. Finally, test the fence line tension and check the connection after the first 24 hours, particularly in high-movement livestock paddocks.
