Ultra-Fab Ultra Chock & Lock (2/Pack) 21-001070 Products

About this item

• STOP THE ROCK!: Eliminates front-to-back trailer motion and reduces side-to-side sway so your RV feels steady, safe, and rock-solid—like parking on concrete instead of quicksand. Quick leverage design makes setup simple, no wrestling match required. Includes two tire locking chocks.
• EXTRA-LARGE FIT, MAXIMUM GRIP: Expands from 3.5" to 5.5" to lock tandem-axle trailer or fifth-wheel tires in place, even on uneven ground. Creates a secure foundation for camping comfort.
• HEAVY-DUTY STEEL MUSCLE: All-steel construction with corrosion-resistant zinc plating. This stabilizer is tough enough for years of road trips and all-weather use. Tire-grabbing teeth bite into tread to prevent slipping, so your trailer stays put instead of shimmying like it’s at a dance party.
• LOCKABLE SECURITY: Accepts a standard padlock (sold separately) to deter theft. Lock it, leave it, and enjoy peace of mind while you’re off adventuring.
• COMPACT & CONVENIENT: Collapses to just 1.5" for easy storage, expands to 5.5" when you need it most. Backed by Ultra-Fab’s lifetime warranty—because forever is hard to beat.
