Solid, interlocking leveling blocks designed for RVs, campers, trailers, and tow vehicles. Stack them to the height you need, then lock the stack together with the included T-handle for no-fumble carry and compact storage.
Finding a perfectly level campsite is rarely a given. The Camco 44521 FasTen Leveling Blocks let you build a custom platform under your RV tires or stabilizer jacks in seconds. The 2x2 interlocking design means blocks snap together firmly -- no sliding, no shifting as you pull forward or back onto the stack.
Each block in the set contributes approximately 1 inch of lift. With 10 blocks per pack you can split the set across multiple tires or run a taller stack under a single wheel. Camco recommends keeping any single stack at or below 4.5 inches to maintain safe, stable support.
Blocks snap together in a 2x2 pattern for a wide, stable base that resists shifting under load.
Dial in precise leveling height one block at a time. Max recommended single-stack height: 4.5 inches.
Pulls up for easy carrying. Twist it down to lock the stack together for neat, compact storage.
Enough blocks to level both drive-side and passenger-side wheels at the same time, or build a taller single stack.
Traditional boards and wedge ramps can creep, split, or tip when a tire rolls onto them at an angle. The FasTen snap-together matrix keeps the platform rigid while you position the rig -- and stays put once you are parked. The wide 2x2 footprint spreads load across soft ground better than a single narrow board.
The T-handle is more than a carrying grip. Twist it clockwise to lock the assembled stack solid, so the whole set travels as one unit in your basement storage or cargo bay. No loose blocks rattling around, no missing pieces at your next site.
