Flap Jack Weigh Safe Block

Meet the Weigh Safe Flap Jack Block—the compact, foldable stabilizer you didn’t know you needed—designed for RVs, trailers, campers, and heavy-duty equipment.

This revolutionary jack block delivers premium stability when deployed and unparalleled portability when stored.

Standing 8″ tall when assembled and folding flat to just 2″, it dramatically reduces bulk and saves valuable storage space without compromising strength or durability.

Crafted from robust, UV-resistant plastics, the Flap Jack supports up to 6,000 lb per unit—enough capacity for most towing setups—while staying lightweight and easy to handle.

The ingenious 3-piece design snaps together in seconds, thanks to built-in neodymium magnets that lock components securely into place—no tools or complicated assembly required.

Each Flap Jack comes with a zippered carry bag for hassle-free storage and transport.

For 2-pack or 4-pack options, one bag accommodates multiple units, making it perfect for compact stowing in RV compartments, trunks, or bumpers.

There’s no maintenance, no bulky gear, and setup takes mere seconds—snap, stabilize, and go.

Whether you’re securing a work trailer or setting up camp, the Weigh Safe Flap Jack Block offers peace of mind, portability, and the stability you need—without the clutter.
