Each assembly consists of a durable, woven polyester webbing strap coiled neatly, attached to a metal ratchet buckle mechanism featuring a zinc-plated or gold-chromate finish for corrosion resistance. This specific lightweight or standard-duty variant is rated for a 150 kg (330 lbs) working load limit, making it ideal for securing lighter cargo on roof racks, trailers, truck beds, or bicycles. To use it, the loose end of the strap is threaded through the center rotating mandrel of the ratchet buckle, pulled taut by hand, and then the handle is pumped up and down to mechanically tighten the strap to the desired tension, ensuring the load remains completely stationary and safe while driving.
