A ratchet strap is a type of tie-down strap used to secure cargo during transport. It consists of a long, durable strap with a ratcheting mechanism that allows for easy tightening and loosening. The strap typically has hooks on each end to attach to anchor points on a vehicle or trailer, ensuring that the load remains stable and secure. These straps are commonly made from strong materials like polyester, which provides resistance to wear and tear. Ratchet straps are widely used in various industries, including shipping, construction, and recreational activities, to prevent shifting or damage to goods while in transit.
