CURT offers two distinct wheel chock solutions: the standard #22800 plastic model for basic utility trailer needs and the heavy-duty #22802 rubber version with permanent mounting hardware for professional applications. The difference between grabbing for chocks in a cluttered truck bed versus having them mounted exactly where you need them? About five minutes per stop and zero lost chocks.
Material Engineering and Cold Weather Performance
The standard #22800 uses durable black plastic construction weighing just 0.88 lbs, making them light enough to toss around without thinking twice. But here’s the catch — that plastic can be brittle in extreme cold. Montana contractors know what -20°F mornings do to plastic. It shatters like glass when you drop it on frozen ground.
The HD #22802 switches to heavy-duty rubber with a high-density steel mounting bracket, weighing 8.59 lbs for the 2-pack. Weather-resistant with UV-stable construction means these chocks handle temperature swings from -40°F to 100°F without cracking, warping, or losing their grip. That’s the difference between replacing chocks every season and having a set that outlasts the trailer.
| Specification | Standard #22800 | Heavy-Duty #22802 |
|---|---|---|
| Material | Durable black plastic | Heavy-duty rubber, high-density steel (bracket) |
| Weight | 0.88 lbs | 8.59 lbs (2-pack) |
| Cold Weather Performance | Can be brittle in extreme cold | Weather-resistant and UV-stable |
| Warranty | Limited Lifetime Warranty (1-year coverage for finish and parts) | 1-year limited warranty |
Dimensional Precision for Equipment Compatibility
Getting the right chock for your wheel size matters when you’re securing expensive equipment. The standard model measures 8-1/4” L x 6-1/8” W x 4-3/4” H and accommodates wheels up to 17 inches wide. That covers most utility trailers, small equipment haulers, and single-axle rigs.
The HD version runs smaller at 5.98” L x 6.30” W x 10.24” H each, but don’t let that fool you. These provide universal fit for most standard passenger vehicles, utility trailers, and RVs. The taller profile creates more contact area with the tire sidewall — critical when you’re chocking dual wheels or larger commercial tires.
Traction Engineering That Actually Works
Both models feature raised tread patterns for superior wheel grip and serrated saw-tooth edges on the base for maximum ground traction. Those saw-tooth edges bite into gravel, packed dirt, and even icy parking lots. The raised tread pattern matches tire tread, creating mechanical lock between rubber surfaces.
Here’s what matters: chocks that slip are worse than no chocks at all. They give you false confidence. CURT’s traction design keeps these planted whether you’re on wet asphalt at a supply yard or loose gravel at a mountain job site.
Professional Mounting Solutions
The HD models include a steel mounting bracket for trailer frame storage, secured with snap-ring clips and wire lanyards. Installation uses supplied self-tapping screws to attach the bracket directly to the trailer frame.
Frame mounting beats every other storage method. No more chocks rolling around the truck bed. No more digging through job boxes. No more “who took the wheel chocks?” conversations. They’re right there on the trailer where they belong. The HD models also feature integrated easy-grip handles — because fumbling with frozen chocks while wearing work gloves wastes time.
Frequently Asked Questions
Q: Will the plastic chocks survive Montana winters?
The plastic can be brittle in extreme cold. For contractors working year-round, the rubber HD version makes more sense. The plastic works fine for seasonal use or indoor storage between jobs.
Q: Can these handle commercial equipment trailers?
The standard plastic version is not recommended for commercial/heavy loads. The HD rubber version handles commercial applications, but verify your specific wheel dimensions against the specs.
Q: How do the mounting brackets hold up to road spray and salt?
The HD version features orange powder-coat & liquid A-coat finish on the steel components. That dual coating system resists corrosion better than basic painted brackets.
Q: What wheel sizes do these actually fit?
The standard #22800 specifically accommodates wheels up to 17” wide. The HD #22802 provides universal fit for most standard passenger vehicles, utility trailers, and RVs.
