Protect your vehicle during lifting to prevent damaging or crushing the pinch welds with metal on metal contact. The Powerbuilt All-in-One Unijack Pinch Weld Saddle Adapter is an extruded rubber saddle adapter that easily installs onto the existing riser saddle of both the Powerbuilt All-in-One and Unijacks. The Pinch Weld adapter is made from high-density rubber material and cut perfectly to fit all pinch weld applications. Simply slide the saddle adapter onto the existing saddle and you’re ready to lift safely. Warning: Remember you will still need to adhere to the capacity, capabilities, and warnings of the jack being used.
