Camco FasTen XL RV Leveling Blocks – Interlock Design, Carrying Handle, 10-Pack

Upgrade your RV leveling routine with Camco FasTen XL RV Leveling Blocks. This 10-pack of extra-large, 2x2 blocks is designed to be more accommodating than standard options, offering a broader base and stronger construction that can adapt to a variety of campsite surfaces. The blocks are 20% larger and built to be 2x stronger, giving you a more confident starting point for your leveling needs while remaining compact enough to carry on each trip.

The interlocking design creates a customizable height profile. By stacking blocks in the Quad-Grid configuration, you can tailor support to your specific wheel and axle setup, helping you achieve a level stance without overstocking on any single block. The XL dimensions, measuring 10.5 inches square and 1.5 inches tall, provide a stable footprint that minimizes wobble on uneven ground.

Carrying and storing the blocks is straightforward thanks to the premium integrated T-handle. Lift the handle to transport, and twist it down to securely lock the blocks together for compact storage in your rig or garage. This built-in feature makes it easier to move between campsites and to keep the kit organized when the site changes.

Designed for broad compatibility, the FasTen XL blocks work with single wheels, double wheels, hydraulic jacks, tongue jacks, stabilizer jacks, fifth-wheel jacks, and tandem axles. For best results, avoid stacking higher than 4.5 inches to maintain stability and even load distribution. The blocks are proudly made in the USA and are offered in a consistent gray color, though colors may vary due to production changes.
