When your trailer rocks every time someone moves inside, setup stops being relaxing. Each Flap Jack block spreads the load with a 9-1/2" × 8-3/8" surface area that keeps jacks steady on the ground. The 6,000-lb capacity per block gives you a solid, stable lift point so your setup feels firm and secure from the start.
Cranking stabilizers all the way down can get old fast, especially after a long drive. At 8" tall when deployed, these blocks take up that space so you don’t have to crank as far to reach the ground. It’s a simple way to save time while reducing stress on your jacks and stabilizers.
Storage space is always tight when you’re hauling gear. Each block collapses flat to just 2" tall, fitting neatly in its zippered carry bag. The folding design and magnetic connections make setup quick and teardown simple, so everything stows cleanly without loose parts rolling around.
Outdoor conditions can be tough on gear, but these blocks are built to last. The UV-resistant plastic construction supports up to 6,000 lbs per block without flexing and won’t rust or corrode over time. It’s dependable strength that keeps performing season after season.
Leveling a larger setup often takes support at more than one point. This set includes four Flap Jack blocks and two zippered carry bags, giving you flexible options for different stabilizer layouts while keeping everything organized between trips. Each block locks firmly into place when unfolded to stay steady under load.
