Getting your trailer stable doesn’t have to be a chore. The Weigh Safe Flap Jack unfolds and locks into place in just seconds, using built-in neodymium magnets that help each of the three pieces snap together without tools or fuss. Once open, it stands 8" tall and provides a steady base that keeps things from shifting while you move around or load up.
When you’re done for the day, the Flap Jack folds flat like a pancake so it won’t hog storage space. Folded up, it measures only 2" high, fitting easily into a gear bag or storage bin. The included zippered carry bag keeps all three pieces together, ready to grab for your next setup.
This block means business when it comes to strength. The durable, UV-resistant plastic design supports up to 6,000 lbs without flexing or cracking. It’s a solid base you can trust under your jacks, whether you’re leveling for the night or stabilizing during maintenance.
From paved pads to dirt pull-offs, stability matters. The Flap Jack’s flat surface area of 9-1/2" by 8-3/8" gives plenty of room for most jack feet to sit securely. It’s sturdy enough for long-term setups and can even be used on gravel or uneven surfaces with proper placement.
Designed with travel in mind, this block is lightweight and easy to carry thanks to its compact fold-flat build and included bag. It’s one less heavy piece of gear to wrestle with when you’re setting up at camp or packing up to head home.

Outstanding. Not only are they thinner the holding case for four make for easier storage. In addition set up and use are a breeze.

After a year of using the Weigh Safe collapsible block I love its convenience. When getting ready to move out of a campsite one of the last things I do is the trailer on the hitch. The Weigh Safe is so quick to remove, collapse, store and get me moving. The number one thing I like about it is its collapsed size without sacrificing strength.
