Each strap is rated for 1362kg breaking strength and 454kg working load capacity. The high visibility yellow straps are constructed of heavy-duty polyester webbing that resists stretching, tearing and rot. The burly steel double J-hooks won't bend like single hooks and offer added security when latched to equipment, trailers and vehicles. And the hooks are rubber coated to prevent scratching your expensive cars and equipment. The oversized comfortable ratchet handles are molded in place and won't fall off. They're big enough to fit gloved hands and offer smooth and sure operation.
