Screw the strain insulator directly into your post — timber, steel, or concrete will all work, though you'll need a pre-drilled hole in steel or concrete. Thread your electric fence wire or tape through the insulator's slot and pull it tight, making sure the wire sits fully in the groove to prevent it slipping under load. The bullnose design helps keep wire seated even when cattle push against the fence, so don't skimp on tightening it down properly. Tips: Check your insulators regularly for cracks or UV damage, especially on north-facing runs — white plastic degrades faster in harsh sun than dark colours, so replace any that look chalky or brittle before they fail and short your fence. Use strain insulators on corners and gates where the fence takes real pressure, not just along straight runs, since that's where wire tension will try to pull free.
