Using a cam buckle is an alternative to using a ratchet strap. Cam buckles are specifically designed with a smaller application in mind, and for securing goods which are more fragile. Because it is only possible to tighten a cam buckle as much as your strength allows, there is less risk of damaging the goods due to over tightening.
Wheel chokers are normally used on recovery vehicles to assist with tying down vehicles to the trailer without damaging alloy wheels. The soft polyester strap is strong enough to take a load of up to 1 tonne, and the polyester eyes replace the old style D-rings to prevent scratching.
