Andersen Hitches EZ Jack Block RV leveling block 3621 — stackable, 2,000 lb rated, made in USA

The Andersen Hitches EZ Jack Block 3621 is a heavy-duty, stackable leveling block designed to stabilize and support RV and trailer jacks up to 2,000 lbs per block.

When you need a reliable, portable foundation for bumper-pull trailers, campers, or stabilizer jacks, the EZ Jack Block provides a simple, durable solution. Built in the USA and backed by a lifetime warranty, this molded block resists slipping and uneven ground settlement while offering convenient handling and optional stacking for extra height.

How does the EZ Jack Block stop jacks from slipping on soft or uneven ground?

The block includes a 2.5-inch recessed post hole that centers the jack foot and prevents lateral movement. Its wide footprint disperses load across more surface area, reducing the chance of sinking on soft soils or gravel.

• 2.5" recessed hole secures post-style jack feet
• Broad base spreads weight to limit ground penetration
• Rigid molded material resists deformation under load

Can I stack multiple EZ Jack Blocks for extra height, and what are the safe limits?

Yes — two EZ Jack Blocks can be stacked to reach additional height (up to roughly 14 inches) when a single block is insufficient. For safety and stability, do not stack more than two blocks at a time.

• Stack up to two blocks for increased lift
• Do not exceed two-block stacks to maintain stability
• Rated to 2,000 lbs whether single or double-stacked

What makes these blocks easy to carry and position at campsites?

Each EZ Block includes finger holes molded into the sides so you can pick up, carry, and accurately place them under jack feet without awkward balancing. The lightweight yet sturdy construction keeps portability high without sacrificing strength.

• Side finger holes for comfortable lifting and placement
• Compact size fits into cargo areas and storage compartments
• Durable construction that remains manageable for one person

Is the EZ Jack Block durable and supported by a warranty?

Manufactured in the United States, the EZ Jack Block is engineered for long service life and comes with a lifetime warranty from Andersen Hitches, covering failures due to manufacturing defects under normal use.

• Made in the USA with quality-controlled production
• Backed by a lifetime warranty from Andersen Hitches
• Designed to resist cracking and deformation under rated loads
