IRONguard's 60-7204 68-9E Rubber Wheel Chock with Eye Hook has a straight-sided triangular profile that reduces the risk of unwanted movement of parked trucks, warehouse equipment, tractor trailers, and box trucks with tire diameters of 17.5" to 22.5". The black molded natural rubber construction provides a durable and economic option for securing parked vehicles because the chock's treads grip the wheels to prevent slippage. When used individually, the chock can hold a parked vehicle on a grade up to 8 to 9%. When used in a pair, the chocks can hold a parked vehicle on a grade up to 20% (second chock sold separately). The attached eye hook has a 7/8" inside diameter for tethering with a rope or a chain to prevent removal from the area. Constructed from black natural rubber, the chock measures 6 x 8 x 9 inches (H x W x D) and weighs 8 pounds. This chock meets Occupational Safety and Health Administration (OSHA) regulation 1910.178 (k).
