Ultra-Fab Super Grip Tandem Axle Chock | Steel, 1-Pack

The Super Grip Chock anchors between the two tires on a tandem axle, using the opposing forces of the wheels to hold everything in place. It's a simple way to stop the front-to-back rocking that happens every time someone moves around inside a parked trailer.

• Anchors opposing wheels of a tandem axle to eliminate rocking motion
• Collapses to 1 inch and expands to 10.5 inches to fit tight gaps
• Heavy-duty steel construction with zinc coating to resist rust
• Handle secured at both ends to reduce slippage while mounting
• Includes a padlock and ratcheting wrench

Sold as a single chock, so pair it with a matching unit if you want both sides of the trailer locked down.
