Wheel Nut Management System that is a Solution, it’s not just an Indicator

Simple, ingenious design reduces the risk of wheel loss by securing
adjacent wheel nuts together and minimizing their ability to rotate.

Why choose Zafety Lug Lock®?

  • Fast and easy to install/remove – flexible, simply fits over two adjacent nuts – can be installed or removed in seconds by hand or with the optional hand tool. See video.

  • Reusable can be reinstalled after removal for wheel end servicing or can be used in similar applications in the event equipment is taken out of service
  • Engineered to withstand extreme temperatures – the flexibility of Zafety Lug Lock® means fast installation and product durability in a wide range of temperatures and weather conditions and ensures lug nut security will not be compromised by overheating wheel ends

Jim arrived with these locks. Mechanic installed them on one trailer and I installed them on another. Without even turning a wheel, I can safely say that these are far and away better than the pointers…
