Btanadi Trailer Hitch Lock with Forged Steel Security Ball, for Knott Avonride 50mm Coupling Heads (575003/575004/575005/575008), Heavy Duty Hardened Steel Anti-Theft Hitchlock for Trailer Security

Btanadi
Why we love it
  • Forged for maximum strength.
  • Dependable protection everywhere you park.
  • Quick and easy installation.
Main Highlights
  • Compatibility Notice: This hitch lock fits ONLY Knott Avonride coupling heads with model numbers 575003, 575004, 575005 or 575008. Some Ifor Williams trailers use these coupling heads — please check the coupling model number before purchase.
  • Precision Fit for Knott Coupling Heads – 575003, 575004, 575005 & 575008: Precision-engineered to fit Knott 575003, 575004, 575005 and 575008 coupling heads with a tight, stable and anti-wobble connection that helps minimise movement. These Knott coupling heads are commonly found on many Ifor Williams trailers and horseboxes, offering dependable and versatile compatibility.
  • Forged Alloy Steel Security Ball – Stronger, Safer Core Design: The forged alloy steel security ball forms a solid, high-density barrier inside the coupling head, offering far greater strength than lightweight alternatives. This premium forged construction provides long-lasting durability and dependable resistance against interference, giving your trailer a stronger level of protection when parked or stored.
  • Secure Clamp Design for Parked Stability: The clamp holds firmly around the coupling to create a stable, low-movement fit that helps deter interference when your trailer is parked. Whether at home, on the yard or at motorway services, the secure hold offers reassuring day-to-day protection.
  • All-Weather, Corrosion-Resistant Build: Constructed from corrosion-resistant steel with a durable protective coating. Designed to withstand rain, frost, mud and summer heat without seizing, delivering reliable year-round performance in every season and in harsher outdoor conditions.
  • Quick, Push-to-Lock Design for Daily Convenience: The hitch lock installs in seconds with a simple push-to-lock mechanism — no key required to secure it in place. The key is only needed when unlocking the device, making daily use fast, convenient and completely tool-free. Designed for regular towing routines, it offers smooth operation with long-lasting reliability.
  • Safety Notice – Not for Use While Towing: This hitch lock is intended for parked or stored trailers only. It must not be used while towing or during vehicle movement. Always remove the lock before driving to ensure safe and proper trailer operation.
