PROLOCK - Successfully Preventing Wheel Detachment for over 20 years

Whether your business has one vehicle or a nationwide fleet, a 4-wheeled van or a rig with many wheels, you need to understand the dangers of wheel detachment and the significant consequences it can cause.
You may think wheel detachment is rare nowadays, but you’d be wrong, and the consequences of being wrong can be devastating.
Here are 2 examples of recent UK news articles that demonstrate the dangers and life-threatening accidents that can occur from a single wheel detachment.
Luckily, in these situations nobody was hurt—but the next time may not be so fortunate.

Now you may already be running a strict maintenance regime and daily wheel checks, which is a fantastic start, BUT if we can go further to minimise this unnecessary risk, it’s our responsibility to do so.
Here at Parma, we stock a range of wheel nut safety devices to suit your operational needs and budget. Our PROLOCK wheel nut locking device is one of our most respected and well-reviewed products.
Made from specialist steel strip with a protective coating, the PROLOCK wheel nut locking clamps secure over 2 adjacent wheel nuts, preventing either from becoming loose. They provide a physical barrier to wheel detachment and give peace of mind that your fleet is operating safely.

Once wheel nuts are fitted and torqued correctly using a specially calibrated tool, PROLOCK devices are fitted using a specialist tool and dead blow hammer to ensure they remain firmly in place. If any wheel nuts begin to lose clamping force, the device continues to hold them securely, preventing disastrous detachment incidents.
With the ability to remove the device during routine torque and operational inspections, PROLOCK offers a versatile, efficient solution and comes in a variety of sizes to suit most fleets.

A well-trusted product, used by emergency services and commercial fleet operators nationwide, the PROLOCK wheel nut locking device prevents the devastation caused by wheel detachment incidents.
