One of the main differences between Cam Buckle Straps and Ratchet Straps is the amount of force that is being used to tighten the webbing. Ratchet Straps use a Ratchet that flows in one direction that allows the cargo to be tightened but never allows the cargo to become loosened unless manually unlocking the tension on the ratchet handle. Cam Buckles utilize hardware called an alligator clip that bites down on the webbing to lock the tie-down webbing into place. The webbings strength can ultimately depend on how tight you can tighten the cargo by hand so if you intend on using heavier loads go with a ratchet strap or alternative.Ratchet Straps can be found in 1 inch, 2 inch, 3 inch, and 4-inch varieties depending on the type of cargo that you are securing working load limits. Cam Buckles can be found in both 1 inch and 2-inch wide webbing varieties. Some of the different types of hardware options for both straps include S Hooks, J Hooks, E Track Fittings, Endless Loop, and Flat Snak Hooks just to name a few of the most popular options.
