Space is always tight when you’re loaded up for a trip. Each Flap Jack block folds flat like a pancake, collapsing to only 2" tall so you can tuck it away in your storage bay, truck bed, or gear bag without taking up much room. When you’re ready to set up, it unfolds in seconds and locks firmly into place for quick use.
Keeping your setup solid is what these blocks are built for. Each one handles up to 6,000 lbs, giving you a strong, stable base that won’t flex or shift under load. The durable, UV-resistant plastic construction stands up to heavy use and outdoor conditions while staying light enough to carry easily.
No tools or fuss when it’s time to level up. The three pieces snap together with built-in neodymium magnets that guide everything into place automatically. That means you can get your jacks or stabilizers set fast and move straight on to relaxing.
Every detail is made for convenience on the go. Both blocks fit neatly into the included zippered carry bag so they stay clean and organized between stops. It’s a simple way to keep your gear together and ready for the next setup wherever the road takes you.

Very easy to set up and take down,
Great idea and product. Haven’t had a chance to use them yet though!
I think it's a worthwhile item, as it allows added storage space.
Awesome Product. Eliminates hauling a box of pieces of wood!
Thanks Etrailer for fast shipping and delivery, little bit of a puzzle to setup at first but got the hang of it pretty quick. Heading out this weekend so will try them out, looks to be high quality product.
We love these. So much better than the hard plastic. And compact a store.
Works as advertised.
Used them for the first time this last weekend. Love how sturdy they are and the magnetic feature is fantastic! They took the place of 16 of the stackable blocks in my use case. These were much easier to use then the pile of blocks i normally do for my rear stabilizers. Time will tell how they hold up but i am thinking they will do well.
I'm on the fence. We camp in different areas and surfaces. They're great if you are on a flat level surface.
We converted to these from wood blocks. So much lighter and they store better.
excellent product! I use them every time I go camping and when the rv is at home to stabilize it.
Product is great, but the delivery driver left the package on the bottom step and it was raining only about three more steps and it would have been on the porch not out in the rain.

I think they work good but they need to be a bit bigger. I have snap pads when I am on concrete. But the pads stick over the stabilizing blocks. Also they don’t feel to stable on unlevel ground too.

Yeah, I can totally see how these would be several steps up from 16 bricks! That's awesome! We tried these out the other day, I thought the space saving design was pretty neat, but didn't consider the ease of just using these blocks instead of bricks and what not. Huge improvement!
