The Camco FasTen Big Blocks are engineered to be placed beneath stabilizer jack feet to spread weight over a larger area and create a steady, level foundation. Constructed for repeated use and designed to nest together for compact storage, these bases simplify stabilization and free up your regular camper leveling blocks for other tasks.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these Big Blocks improve stabilizer jack performance?\u003c\/h3\u003e\n\n\u003cp\u003eBy increasing the surface area under the jack foot, the Big Blocks reduce ground pressure and prevent the jack from digging in. That means fewer adjustments, less chance of tilting, and a more secure campsite setup.
