Deluxe Tire Locking Chock by BAL at RVWholesalers.com
Fit between tandem tires, it locks wheels by applying force to both tires. Aids in trailer stabilizing and prevents tire shifts. A hand-operated plated ratchet wrench (Model 841025, included) turns a drive nut, extending the chocks against the tires for locking and retracting the chucks for removal. Requires 2-1/2″ clearance between tires. Opens to 10″.
