The OneStep XL wedges in between the tires on a tandem axle trailer or RV, locking the wheels in place so the rig doesn't rock and roll while you're inside. It's built for tandem axle spacing from 16" up to 30" long.
The design lets you set it and pull it back out from a standing position, so there's no kneeling down and reaching under the trailer at the campsite.
Sold as a single chock (qty 1); pair with a second for chocking both sides.
