This is a brand new Sliding Bridge Jack we got with our lift. We bought two and this one was 6 months later being shipped to us and we found that the one is all we use. It is 12K lift with adjustable slide arms to fit different lifts, adjustable pads in height and width for vehicles. Sorry the dust on the lift sitting in Garage for 2 years. Cost over $1100.00 new, sell for $700.00
