Camco FasTen RV Leveling Blocks — 10-Pack 8.5" x 8.5" x 1.5" Bright Yellow, Interlocking Quad-Grid for Stable RV & Trailer Support

Camco FasTen RV Leveling Blocks are a 10-pack of interlocking, high-strength polymer blocks designed to stabilize and level RVs, trailers, and campers on uneven ground.

When you arrive at a campsite with uneven terrain, quick and reliable leveling is essential for comfort and safety. These bright yellow Camco FasTen blocks stack together to create a customizable base for single or double wheels, tandem axles, and many jack types. Built with a quad-grid load-bearing design and a patented interlock, the blocks offer consistent support and integrate with other Camco FasTen accessories for extended versatility. Lightweight, portable, and made in the USA, they simplify setup and tear-down so you can focus on the trip.

How do these leveling blocks make RV setup faster?

FasTen blocks eliminate trial-and-error with a simple stacking system that creates a stable platform quickly. The interlocking grid prevents slippage so you can adjust height without constantly re-stacking. The integrated T-handle reduces handling time and stores neatly when not in use.

• Ten 8.5" x 8.5" x 1.5" blocks for incremental height adjustments.
• Interlocking quad-grid design keeps stacks secure under load.
• Built-in T-handle for fast carry, lock, and compact storage.
• Compatible with wheels, axles, and multiple jack types for flexible use.

What kinds of RVs and jacks work with these blocks?

These blocks are made to support a broad range of recreational vehicles and common jack styles. They can be used under single or dual wheels, tandem axles, and with hydraulic, tongue, stabilizer, and fifth wheel jacks—provided stacking limits are respected for safety.

• Suitable for travel trailers, fifth-wheel trailers, motorhomes, and pop-ups.
• Works with wheel contact points and jack feet for leveling and stabilization.
• Interlocks with other Camco/FasTen products for taller or wider setups.
• Do not exceed a maximum recommended stack height of 4.5".

Are these blocks durable and safe for heavy loads?

The FasTen blocks feature a quad-grid extreme load-bearing design made from engineered polymer, providing a stable foundation for RV support. Their structural engineering disperses weight evenly across the stack, and the interlocking profile reduces shifting under pressure to give dependable performance at campsites and rough surfaces.

• Patented structural grid optimizes load distribution and resistance to deformation.
• Engineered polymer construction resists cracking and weather exposure.
• Bright yellow color improves visibility for safe placement and retrieval.
• Manufactured in the USA to consistent quality standards.
