Camco FasTen RV Leveling Blocks 10-Pack, Gray — Interlocking 8.5" Square with T-Handle for Quick Stable Setup

Camco FasTen 2x2 Leveling Blocks are a 10-pack of interlocking polymer RV blocks that stack to stabilize and level campers, jacks, and wheels on uneven ground.

These FasTen leveling blocks from Camco provide a compact, modular solution for creating a steady foundation at campsites, gravel pads, dirt lots, and other uneven surfaces. Each block measures 8.5" x 8.5" x 1.5" and features a quad-grid structural pattern engineered for heavy load distribution. Built-in interlocks keep stacks aligned while a twist-up T-handle locks blocks together for easier carrying and tidy storage. Made in the USA, the set is designed to integrate with other Camco/FasTen accessories so you can adapt your setup as needed.

How do these blocks make RV setup faster and more stable?

The interlocking design lets you build a stable stack quickly without fumbling individual pieces. The grid-reinforced surface spreads weight across the block, reducing pressure points under tires and jacks. The T-handle both secures blocks during transport and snaps into the base for compact storage.

• Interlocking edges prevent slippage when stacked under wheels or jacks
• Quad-grid engineering distributes load for improved stability
• Twist-up T-handle locks blocks together for carrying and storage
• Compact 8.5" square footprint fits single or double wheel placements

Which RV parts and surfaces are these leveling blocks compatible with?

These leveling blocks work with single wheels, double wheels, tandem axles and many jack types including tongue, stabilizer, hydraulic, and fifth-wheel jacks. They also perform well on common campsite substrates like gravel, packed dirt, and grass. For safety, stacks should not exceed 4.5" in height.

• Fits under single and double wheel configurations as well as tandem axles
• Compatible with hydraulic, tongue, stabilizer, and fifth-wheel jacks
• Suitable for campsites, gravel pads, dirt lots, and firm soft-ground areas
• Maximum recommended stack height: 4.5" to maintain rated stability

What features help with transport, storage, and long-term use?

The FasTen blocks include a built-in T-handle that lifts for transport and twists into the base block to lock stacks together. Durable polymer construction resists cracking and moisture, making them low-maintenance for long-term outdoor use. Because they’re made in the USA with a patented design, you get consistent sizing and reliable fit when combining pieces or connecting to other Camco accessories.

• Integrated T-handle lifts for carrying and locks into base for compact storage
• Durable polymer resists water, rot, and UV deterioration with normal use
• Patented manufacturing ensures uniform dimensions and reliable interlock
• Pairs with other Camco/FasTen products for expanded leveling options

How many blocks do I need and how should I plan stacks?

This 10-pack gives flexible height options—use single blocks for small adjustments or multiple stacked for larger lifts. Plan stacks beneath wheels or jack pads, keeping each stack stable and within the 4.5" recommended stacking limit. Mix with other Camco leveling products if you require additional height or larger footprint support.

• 10 blocks per pack allow multiple stack combinations for fine height tuning
• Use even-numbered stacks under dual wheels for balanced support
• Do not exceed 4.5" stack height to avoid stability risk
• Combine with Camco leveling ramps, big blocks, or jack pads for more options

Who is this for: Camper owners, RVers, and trailer owners who want a lightweight, modular leveling solution that’s simple to carry and store. These blocks suit weekend campers and long-term travelers who need dependable, easy-to-adjust support for wheels and jacks on uneven ground, and anyone who prefers American-made accessories that work with a broader Camco ecosystem.
