The RJ-7 rolling bridge jack from BendPak raises two wheels off of four-post lift runways, making automotive service such as brake jobs and suspension work easier. Telescoping roller design allows the runways to be adjusted for different tread widths, so a variety of vehicles can be serviced without the need for an adapter, the maker said. Each jack has a 7,000-pound maximum capacity and is designed for use with BendPak HD-14 series lifts. The included commercial-grade air-hydraulic pump requires 125 psi and 10-20 CFM.
