It can easily become a dangerous situation while changing your tyres: many people just rely on using a jack. A big mistake, because a jacked-up vehicle can roll away despite being secured with a car jack and can cause great damage. The foldable wheel chock UltraStop PRO by HEYNER® ensures secure holding of your vehicle or trailer. The particularly robust quality and high-end workmanship enable an axle load of 1000 kilograms per chock. In addition, the premium brake wedges convince through quick and easy handling.
