jackstands
Stationary car supports
Jackstands are metal supports used to hold a vehicle safely off the ground after it has been raised with a jack.
They provide stable, fixed support for working underneath a car—never trust a hydraulic jack alone: Once you've lifted the car, set it on jackstands before crawling under.
They typically come in pairs and adjust to different heights.
