Fast & Easy Trailer Stabilization
Using the Trailer Jack block under your jack(s) means your jack doesn’t need to extend down as far, saving on wear and tear over time. And because the jack doesn’t need to extend fully, there’s less stress on it from movement - it’s a win-win for RVs and Trailers.

First all Andersen products are well thought out and supported very well. My only bad experiences have been how easy the hitch block set screws strip under full torque. The jack blocks are superb with only the magnets corroding as their issue (please note that is not a complaint as I understand that dissimilar metals in contact will corrode in an outdoor environment).
But in all cases the Andersen support team has been fantastic. I would recommend Andersen over all trailer hitches.
Best regards
