bullke Square Trailer Jack Block 1-Pack — USA-Made Recycled Plastic, 10,000 lb Rated RV Leveling Pad

The BULLKE Square Trailer Jack Block is a heavy-duty, USA-made recycled-plastic pad that gives RVs, trailers, and campers a stable, durable base for leveling and jack support.

When setting up an RV, trailer, or 5th wheel, a reliable jack base prevents sinking, tilting, and damage to jack feet on soft or uneven ground. The BULLKE square jack block is designed to be simple to position and carry while providing a sturdy platform rated for substantial loads when used correctly. Made from recycled plastic in the United States, this one-pack block suits a variety of jack types including tongue jacks, foot jacks, post jacks, stabilizer and scissor jacks.

How much weight can this jack block safely support?

The block has been engineered for heavy loads when installed on firm, level ground with the jack foot centered. Used alone, the block is rated for loads up to 10,000 lbs; when combined with BULLKE Flex Pads it supports up to 18,000 lbs under the same proper-installation conditions. Always verify placement, center the jack foot, and avoid soft or irregular surfaces to reach rated capacity.

• 10,000 lb rating without Flex Pads on firm, level ground
• Up to 18,000 lb rating when paired with BULLKE Flex Pads
• Ratings apply with jack foot centered and correct placement

What surfaces are appropriate for using the BULLKE block?

For reliable performance, place the block only on firm, level ground. Avoid gravel, loose stones, raised rocks, or uneven terrain; these conditions can reduce stability and void load expectations. Before placement, clear debris and inspect the ground so the block sits flush and the jack foot is centered.

• Best on packed dirt, compacted gravel, concrete, or asphalt
• Do not use over loose rocks, raised stones, or severely uneven ground
• Clear the area to allow the block to sit flat for maximum stability

How do I use and store this jack block effectively?

Using the square design is straightforward: position the block, center the jack foot, and then operate the jack normally. Its compact shape makes it easy to carry, stack, and stow in RV storage bays or trailer compartments. The recycled-plastic material resists weather and repeated use, so routine cleaning and dry storage when possible will prolong service life.

• Place block flat, center jack foot, then raise or lower jack
• Stack or nest in cargo spaces for compact storage
• Wipe clean after use; store out of prolonged UV exposure for longevity

Its square form is designed for easy handling and consistent contact with jack feet. The product also integrates into a system with optional BULLKE Flex Pads for higher load capacity, offering a scalable approach to heavier rigs.
