Secure your RV or trailer with the Andersen Hitches Trailer Jack Block, engineered for heavy-duty support and effortless placement. The built‑in magnet on the top locks directly onto your trailer’s round jack pad, ensuring the block stays perfectly positioned even as the jack is lowered. This feature eliminates shifting and provides reliable stability for both stabilizer and leveling jacks.

Designed to handle demanding loads, each block is rated for up to 8,000 lbs when single‑stacked and 1,500 lbs when double‑stacked. The 8‑inch height offers ample clearance for significant grade differences, while the wide 12‑inch base distributes weight evenly, resisting tipping on soft or uneven ground. Finger‑style recesses on the sides allow for easy placement and removal, even in tight spaces or from awkward angles.

Made in the USA, Andersen Hitches backs every block with a lifetime warranty, giving you confidence that your equipment will perform whenever you set up camp. Whether you’re leveling a large travel trailer or stabilizing a small RV, this jack block delivers the durability and convenience you need for a safe, level ride.
