Designed to fit the axles of Semi-Trucks and trailers up to 6" inches in diameter. The jack pad is made to fit the majority of 12 Ton bottle jacks with rams of 1.69" - 1.72" diameter. The pads low profile design makes it easy to place and maximizes the usable stroke of the jack.
Safe Jack pads for rounded structures increase safety significantly compared to using the jack ram directly against the structure because the pad supports the load over a much wider area. The larger contact area adds stability and decreases the load forces on the lift point. The size and shape of the pad makes the jack far less likely to slip or tip when jacking against a rounded surface.
