The flat polypropylene webbing strap is made of durable, waterproof polypropylene material, making it ideal for outdoor activities like camping and boating, as well as various uses including backpacks, luggage straps, cargo securing, and crafts. Known for its high strength, wear resistance, and lightweight portability, this strap is easy to work with -- simply select the appropriate size, cut it to the desired length, and install as needed. To prevent fraying, lightly melt the cut edges with a lighter. Please note that sizes are hand-measured, so a slight tolerance of +/-0.1 inch may apply.
