Bright, safety orange wheel chock ideal for commercial vehicle maintenance and industrial loading application. Guardian wheel chocks firmly stop transport truck and tractor trailer tires from creeping or rolling while the vehicle is parked, and Guardian wheel chocks meet OSHA standards to help keep workers and drivers safe on the job. The polyurethane wheel chock measures 8" x 7" x 6" overall with a high-traction surface designed for maximum friction between vehicle tire and parking surface. Each chock includes a recessed carrying handle and a built-in mounting hole for securing with rope or chain.
