BAL's Wheel Chocks: Engineered Stability for RV and Trailer Owners
When it comes to keeping your RV or tow-behind trailer firmly in place at the campsite, few names carry more credibility than BAL — A Division of Norco Industries. With a legacy spanning more than six decades of manufacturing for the recreational vehicle industry, BAL has built a focused lineup of wheel stops and chocks that go well beyond simple blocks of rubber or plastic. These are precision-engineered, patent-backed solutions designed specifically for the demands of tandem-axle trailers, fifth wheels, and travel trailers.
The X-Chock: A Patented Approach to Tire Stabilization
BAL's flagship wheel chock product — the X-Chock® Tire Locking Chock — represents a fundamentally different philosophy in trailer stabilization. Rather than simply wedging a block against a tire, the X-Chock is placed between tandem tires and uses opposing force to lock both wheels simultaneously. What sets it apart is that it works with the tires' natural movement instead of against them, providing a more effective and durable lock. The Standard X-Chock (models 28010/28012) carries U.S. Patent #8,365,875 and retracts down to just 1 3/8" — making it slim enough to fit even the tightest axle gaps — while extending up to 10" to fill the space between tires firmly. Each unit ships with a plated ratchet wrench with a comfort bumper grip, and can be secured with an optional padlock for added theft deterrence.
For trailers with wider axle spacing — such as those from Bullet, LaCrosse, PrimeTime, Passport, and North Trail — BAL also offers the X-Tended Fit X-Chock (models 28014/28024), which extends up to 17" to accommodate wide-track axle configurations. Both X-Chock variants feature a rust-inhibitive zinc coating for long-term durability in outdoor conditions and are Made in the USA.
The Deluxe Tire Locking Chock: A Proven Classic
The Deluxe Tire Locking Chock (model 28005) is BAL's time-tested solution for tandem-axle trailers. Covered under U.S. Patent D347821, it fits between tandem tires and locks wheels by applying opposing force to both — aiding in trailer stabilization and preventing the tire shift that causes unwanted rocking and swaying. A hand-operated plated ratchet wrench (model 841025, included) turns a drive nut to extend the chock firmly against the tires or retract it for easy removal. The entire unit has a rust-inhibitive plating for long service life and is lightweight enough to toss in a storage compartment when not in use.
Why BAL Chocks Stand Out
- Dual-tire opposing-force design — locks both tandem tires at once for superior stabilization versus single-tire chocks
- U.S. patents on both the X-Chock and Deluxe Tire Locking Chock lines, reflecting genuine engineering innovation
- Rust-inhibitive coatings on all steel hardware for durability through seasons of outdoor use
- Made in the USA — the X-Chock line is manufactured domestically
- Multiple size options — standard and X-Tended Fit variants cover a wide range of axle spacing configurations
- Lockable design — compatible with optional padlock for campsite security
