Deluxe Tire Locking Chock
Use this chock to fit between tandem tires and it locks wheels by applying force to both tires. It also aids in trailer stabilizing and prevents tire shifts. A hand-operated, plated ratchet wrench (included) turns a drive nut, extending the chocks against the tires for locking and retracting the chocks for removal. They require a 2-1/2 inch clearance between tires and will open out to 10 inch. They also have a slot for a padlock to make your RV extra secure (not included, sold separately).
