EKON OX BLOX trailer jack block 10,000 lb capacity — black stackable, UV‑resistant support pad

OX BLOX is a heavy-duty, stackable trailer jack block by EKON that provides a stable, 10,000 lb-rated support pad for trailer jacks, stabilizers, and camper leveling needs.

Designed and manufactured in the United States from 100% recycled compression-molded plastic, the OX BLOX combines a patented geometry with UV- and temperature-resistant material to deliver durable, wobble-free support on uneven or soft ground. Lightweight handles and a compact footprint make it easy to carry and store in an RV bay or pickup bed, while the ability to stack units lets you gain extra height without sacrificing rated capacity.

How does OX BLOX keep a trailer steady on soft or uneven ground?

The patented shape spreads load and resists sinking and tipping so jacks won’t wobble on gravel, dirt, grass, or pavement. Its engineered contact surfaces and interlocking stack fit reduce lateral movement and transfer forces evenly into the ground.

• US patent-backed design prevents rocking and twisting under load
• Wide base distributes pressure to reduce sinking
• Interlocking top/bottom surfaces keep stacked units aligned

Can I stack OX BLOX for more height and still trust the weight rating?

Yes — you can stack multiple OX BLOX for additional lift while maintaining the 10,000 lb rating per block assembly. The blocks are engineered to bear heavy loads even when stacked, making them useful as tongue jack risers, camper leveling blocks, or stabilizer pads.

• Stackable design allows incremental height adjustments
• Each block retains the 10,000 lb capacity in stacked configurations
• Secure interlock prevents slippage between stacked units

What materials and weather resistance features does OX BLOX offer?

OX BLOX are made from recycled plastic through compression molding, resulting in a dense, long-lasting pad that resists UV damage, temperature extremes, and cracking. That construction keeps them reliable for years of outdoor use, from seasonal storage to heavy-duty job site demands.

• 100% recycled plastic — sustainable and robust
• Compression-molded for structural strength and impact resistance
• UV and temperature resistant to withstand sun and cold

How easy are the blocks to handle and store while traveling?

Each OX BLOX weighs just over eight pounds and includes molded grab handles so you can move them quickly around your trailer or truck. Their compact footprint stacks neatly in storage bays, under seats, or in a pickup bed without taking up much room.

• Integrated handles for fast carrying and positioning
• Lightweight design reduces lifting strain for one person
• Compact stacking minimizes storage space requirement

Who is this for: OX BLOX is intended for RV owners, travel trailer and fifth-wheel operators, boat and horse trailer users, and anyone who needs dependable jack support on uneven or soft ground. It suits weekend campers, full-time RVers, landscapers and tradespeople who want a portable, reusable pad that resists sinking, cracking, and weathering while providing confidence-inspiring stability.
