The Torin BIG RED TD3553 safety wheel chock tire stop is crafted with heat-treated, drop-forged steel for added strength. It's designed to perform better than plastic or resin-made wheel chocks. Includes 1 pair (2) which are easy to operate and are intended for use with jacks and jack stands (sold separately). The high-visibility red color is easy for the driver to spot. A polished finish makes the wheel chock dirt-resistant and provides anti-rust protection. It features a small body with a foldable design that allows the wheel chocks to flatten after use, making carrying or storing easy. Ideal for use when using a jack on cars, trucks, vans, and more. Contoured shape fits most residential and commercial vehicle tires during application..
