"The Link MFG LB20 bifold loading ramp is made from extruded high-strength aluminum and easily installs into any vehicle with a flat surface. The unique pull-style, quick-release latch makes the ramp easy to deploy and allows for bumper clearance of most vehicles. The ramp features a low-profile transition threshold and only takes seconds to deploy, increasing the ease of use while also reducing dangerous lifting and possible equipment damage. The gas spring-assist lifting mechanism balances the weight of the ramp for ease of use. The walking surface of the ramp has a ribbed aluminum finish for safety and durability, while wheels at the bottom of the LB20 assist with moving the ramp over flat surfaces. All LB20 ramps ship fully assembled, include a wheel kit and are mounted just inside a vehicle's rear door. The ramp stores vertically and folds in half to collapse to roughly 7.5"" in depth. | Link MFG LB20 Bifold Loading Ramp 7842-A203"
