How the Trailer Jack Block Works
Place the Andersen Trailer Jack Block under your trailer jack and let the built-in magnets hold it in position. As you lower your jack, the block stays perfectly centered, creating a stable base without the need to reposition or adjust. Because the block reduces how far your jack needs to extend, setup becomes faster and requires less effort. At the same time, the wide base helps distribute weight more evenly, improving stability and reducing the risk of sinking on soft or uneven ground. The result is a quicker, smoother setup with fewer steps and more confidence that your trailer is secure.
