Ultra-Fab 21-001080 Chock and Lock XL Wheel Stabilizer for RV Tandem Axle Trailers

The Ultra-Fab 21-001080 Chock and Lock XL is a professional-grade wheel stabilizer designed to eliminate front-to-back rocking motion on tandem axle RV trailers and fifth wheels. This innovative stabilizer works by anchoring the opposing wheels of tandem axles, causing the trailer wheels to work against each other to arrest any motion regardless of ground surface or slope.

Key Features:

• Heavy gauge all steel construction with corrosion resistant zinc plating
• One-piece design collapses to 4.25 inches and expands up to 10 inches
• Fits wheel spacing between 4.5 and 10 inches
• Easy to use lever operation with E-Z grip handle
• Lockable design to minimize theft (padlock not included)
• Super grip tire louvers reduce slip

This XL model provides superior stabilization for larger RVs with wider wheel spacing. Simply place the chock between your tandem tires, expand using the threaded rod adjustment, and press the handle down to lock it firmly in place. The unit stays compressed between your tires to eliminate movement while parked, providing a stable platform for camping or storage.
