Trailer Jack Block Andersen



The Andersen 'Trailer Jack Block' eliminates nearly all of the movement in your parked RV or Trailer! Each block comes with built-in magnets so you can attach each block to the bottom of your stabilizer and hit auto-level - no need to check and adjust each block. Fast and super-convenient! 

For best results, use two blocks at the front and two in the back of your RV or Trailer. For trailers with more than 4 stabilizer jacks, use one block per stabilizer.
