The Metal Cam Strap pictured above is made with 1 inch Polyester Webbing. Polyester webbing 3/4 inch has a breaking strength of 2500 pounds with a thickness of 0.060 of an inch.Whether you need cargo management, trailer tie downs, ATV and motorcycle straps, or just straps for river rafting, Strapworks has the perfect solution - metal cam polyester straps. The most common use for cam straps are a strap used to tie down or secure heavy loads, typically on trailers or in the bed of trucks. Cam buckle straps may be considered the "duct tape" of the strap world, but they do have limitations. A strap is only as strong as its weakest link. The safe working load is one-third the breaking strength For example, Strapworks flat nylon webbing 3/4 inch has a breaking strength of 2500 pounds, so a safe working load is 833 pounds. You also need to consider your hardware and stitching. You also need to calculate your safe working load for your stitching. Strapworks engineers the stitching to meet the next weakest link (usually the buckle). When in doubt, buy 1 strap and test it for your application. Please keep in mind the characteristics of the different types of webbing when ordering straps. Metal Cam Polyester Straps have the same attributes and characteristics as patterned polyester. Strapworks' polyester webbing is also sublimated, but is sublimated in solid colors. Polyester has all of the benefits of Flat Nylon, high breaking strength, high abrasion resistance, soft, smooth, and shiny. It also has the benefits of polypropylene, low water absorption, high UV protection, and it is also mildew and rot resistant. Strapworks "Patterned Polyester" is polyester that has been sublimated. Sublimation is a process that virtually tattoos the ink into the webbing by turning a solid ink into a permeating gas. This process is done in house and it allows for great detail and vivid custom colorfast colors. Polyester is the only material we carry that is consistent in its ability to be sublimated. Cam Straps made with heavyweight polypropylene webbing are suitable for medium duty outdoor applications. Heavyweight polypropylene webbing has excellent UV protect and does not absorb water quickly giving it better better resistant to mildew and rot resistance. However, polypropylene does not have good abrasion resistance, so it is not recommended for use against rough edges. Cam Straps made with lightweight polypropylene webbing are ideally suited for outdoor light duty use. Other than breaking strength and webbing thickness, they have the same attributes as heavyweight polypropylene webbing. The sublimation process may take an extra 2-3 days to fulfill your order.
