How do Stainless Steel Ratchet Tie Downs work?

Stainless Steel ratchet Tie Downs are the combination of strapping and ratchets (and some times hooks to fasten them), used to secure cargo during transport. When used correctly, these straps can support large weights. To use the ratchet straps, thread the strap through the metal ratchet and then crank the ratchet to tighten it. To release the strap, press the release tab and open the ratchet.
