The IWI 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). Specifications H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Wheel chocks (also called wheel immobilizers or chock blocks) are designed to help prevent vehicles from accidentally rolling when parked, especially on a grade. Primarily for the safety of workers when a vehicle is undergoing maintenance, or being loaded or unloaded, use of wheel chocks can also reduce property damage from accidents and loss from spillage during loading operations. Wheel chocks are typically wedge shaped. The required size depends on the weight of the vehicle, the size of the tires, the steepness of the grade, and the quality of the road surface. Large wheel chocks are usually made of a durable material with a high strength-to-weight ratio, and include handles or ropes to facilitate manual deployment. Occupational Safety and Health Administration (OSHA) and Mine Safety and Health Administration (MSHA), both agencies of the U.S. Department of Labor, require wheel chocks in several specific situations (including when parking on a grade and during loading operations). Independent Warehouse, Inc. manufactures loading dock and industrial accessories. The company, founded in 2002, is headquartered in Sparks, NV.
