Use this 4-post bridge jack with your BendPak HD-9 series four-post car lift for increased versatility and productivity. The RJ45LP rolling bridge jack is ideal for any shop with the HD-7 series or HD-9 series four-post lift model, arguably the most popular and versatile four-post car lifts on the market. Featuring an impressive low-profile design, the RJ45LP lift pads sit just 4.25" from the runway surface and is equipped with easy-to-roll wheels for effortless gliding down the runway track. For those with an HD-7 or HD-9 four-post lift that are in need of wheel service capability, the RJ45LP offers extreme versatility and convenience, in a low-profile package. The RJ45LP and RJ45W rolling bridge jacks are essentially the same except for two specifications: First, the RJ45LP minimum drive-over height is 4.25" and the RJ45W minimum drive-over height is 4.5". Second, the RJ45LP maximum arm reach is 61" wide and the RJ45W maximum arm reach is 57" wide. Take a look at the RJ45W Bridge Jack. With three lock positions to choose from, it's easy to find the perfect height to perform wheel and brake service. For additional height, raise the car lift to its max height, add the stackable adapters and raise the rolling bridge jack as high as it will go. Now you have more access to the undercarriage than ever before.
