Normally, the standard ratchet straps are often made from the polyester webbings. If you are looking to purchase the strap, the most important thing to consider is to check the durability of a strap. The advantages of using heavy duty ratchet straps are able to carry more weight even with a small stretch. If you require an extra stretch for your tie down, you just go for nylon straps that have longer durability. In addition, you also have a great option to customize your own ratchet strap by simply adding the extra hooks and buckles as well.
