ROBLOCK 4-Pack Trailer Jack Block with Bag — Heavy-Duty RV Stabilizers for Tongues, Posts, and More

Overview

ROBLOCK 4-Pack Trailer Jack Block with Bag is engineered to stabilize your RV, travel trailer, or camper tongue across a variety of terrains. Cast from UV-resistant plastic, these blocks resist dirt and oil while maintaining a rigid, steady base. The result is a solid platform that helps keep your jack aligned and your rig feeling secure as you settle in for the night.

Why this setup can help on your next trip

Campgrounds and driveways aren’t always perfectly level. With a wide 11 x 11 inch footprint and a low profile, these blocks distribute weight evenly and reduce sinking into soft ground. A built-in drain hole helps water and moisture escape, helping to keep metal components drier after rain or early-morning dew.

• Heavy-duty construction resists deformation and cracking over time
• Anti-slip textured surface with recessed post holes for secure placement
• Reinforced bottom and thickened sides enhance stability
• Drain hole design promotes drainage and reduces rust risk
• Wide compatibility with scissor jacks, tongue jacks, posts, feet, and stabilizers

In practice, the blocks can simplify setup by providing a stable base from the moment you park. The 11 x 11 x 4.3 inch size fits under many tongue jacks and stabilizers, helping to prevent rocking on uneven ground while you connect utilities or level the trailer.

Portable and organized

Each block weighs 2.87 pounds and ships with a stowable bag. The compact design and included handles make it easy to carry, stack, and store between trips. When you’re ready to move, the lightweight build reduces fatigue and supports quick campsite adjustments.

• Lightweight and easy to transport
• Bag for compact storage and transport
• Rugged, dirt- and oil-resistant material for long life
