Ultra 21001060 Chock & Lock Wheel Stabilizer for Tandem Axle RVs and Trailers

The Ultra Chock & Lock is a heavy-duty wheel stabilizer designed to eliminate annoying front-to-back trailer movement by locking tandem wheels against each other. This innovative stabilizer creates a rock-solid, secure setup at the campsite by anchoring opposing tandem tires together.

Key Features:

• Expands from 1.5 inches to 5.25 inches to fit most dual-axle trailers, fifth wheels, and RVs
• Heavy-duty steel construction with corrosion-resistant zinc plating for long-lasting durability
• Super Grip tire louvers with aggressive tread that bites into tire surfaces to prevent slipping
• E-Z Grip handle provides superior leverage for quick installation and removal
• Collapses flat for compact storage when not in use
• Includes provision for padlock to secure the stabilizer in place
• One-piece design for easy setup in minutes

This stabilizer works by placing it between tandem tires and expanding it until the give between the wheels is eliminated. The opposing forces of the tandem wheels lock everything in place, dramatically reducing trailer rock and improving overall stability. Ideal for RV owners and trailer enthusiasts who want a more comfortable, stable camping experience.
