Sewing enthusiasts and crafters, this heavy-duty #10 plastic zipper is perfect for your big projects! The 72-inch length (73 inches end to end) makes it ideal for sleeping bags, boat covers, canvas projects, trampoline nets, tents, dog beds, and other large items that need reliable closure. The resin teeth are environmentally friendly, burr-free, and zip smoothly without catching. The double pull sliders mean you can open the zipper from either end, which is super convenient for sleeping bags, mattress covers, and other applications where you need access from different sides. When zipped, the full width measures about 1.4 inches, giving it a substantial, professional appearance. The black color is versatile and works with most fabric colors and types. The separating design means the zipper completely comes apart when opened, unlike conventional zippers that stay connected at one end. This heavy-duty construction can handle frequent use and tougher conditions than standard dress zippers. Whether you're repairing existing gear or creating new projects from scratch, this zipper provides the durability and functionality you need. The quality is evident in the smooth operation and sturdy teeth that won't break or deform under pressure. Perfect for marine applications, outdoor gear, heavy-duty bags, and any project where you need a zipper that can handle real-world use and weather exposure. One zipper per package, ready for your next big sewing adventure!
