Get a solid, level campsite on any surface. The Camco FasTen leveling blocks stack and interlock to give your RV, trailer, or fifth wheel a stable, non-slip platform -- no sliding, no shifting, no fumbling with loose blocks under your tires.
Uneven campsites are a fact of life. The Camco 44515 FasTen leveling blocks are designed for exactly this problem. Each block adds 1 inch of lift, and they stack together in a tight interlocking pattern that keeps them from shifting under load -- whether you're running single tires, duals, or tandem axles.
The integrated T-handle locks the entire set together for carrying and storage, so you're never chasing blocks across a gravel pad. At 14 lbs for the complete set of 10, they're heavy enough to stay put but light enough to toss in a storage bay without reorganizing everything else.
Blocks lock together under tire load and do not slide. Compatible with older-style Camco blocks and chocks for mixed setups.
Material is UV-stabilized so it resists sun degradation during extended outdoor storage and use in all seasons including winter.
Carry and store the entire set of 10 as a single unit. No loose blocks rattling around your bay or gear bin.
Works with single wheels, dual wheels, hydraulic jacks, tongue jacks, stabilizer jacks, fifth wheel jacks, and tandem axles.
Each block provides 1 inch of lift. With the set of 10, you can stack up to a maximum of 4.5 inches of lift -- the manufacturer-specified safe limit before a coach may become unstable. Plan your stack before you pull onto the blocks; 4 to 5 stacked blocks covers the vast majority of real-world campsite grade corrections.
The 17-inch length and 8.5-inch width give these blocks a footprint wide enough to support dual rear tires and large jack pads. Confirmed compatible applications include:
UV-stabilized polypropylene holds up in freezing temperatures, so these blocks can remain under your rig or jacks during winter storage without cracking or becoming brittle. This makes them a practical choice for seasonal and full-time RVers alike.
Camco manufactures the FasTen 44515 blocks in the United States. The set carries a limited 90-day manufacturer warranty against defects in materials and workmanship.
