The AL-KO Stabilform-push-in supports are extra robust because of extruded profiles, crimped side rods and strong, rolled trapeze threaded spindles. Long durability due to the hot-dip galvanised surface. Info: brackets are provided for the brace support of the caravan. They may not used as jack for tyre change or similar. With an untwisting position of 45° the maximum load will be reached. By changing the untwisting position below 45° the maximum load will be reduced.
