Wire Strainer
🔧 A wire strainer multiplies your tension force
The simple turn‑and‑lock mechanism isn’t just convenient — it gives you mechanical advantage, meaning a small twist can generate hundreds of pounds of tension in the straining wire. That’s why they’re ideal for keeping crop bars, ridge wires, and side bracing tight without specialist tools.
🌬️ Proper wire tension improves polytunnel wind resistance
A well‑tensioned straining wire helps the frame resist lateral movement. Even a small amount of slack can increase wind‑induced flex, which accelerates wear on polythene and fittings. A £2 strainer can meaningfully improve the polytunnels' stability.
