A ratchet strap you don't have to thread. With the ratchet handle fully open, open the side gate, drop the strap into the middle of the spool and close the gate. Loading it in the middle helps stop the ratchet pulling to one side. Engage the handle again and the gate locks itself in place. Unloading works the same way in reverse.
Check the rating on the strap's label against the load before you use it. It's a lashing strap, so never lift with it, and don't use a strap that's cut or frayed.
